The OP is horribly outdated now. Uggh, OK, I made my own list.
reminder not all the URLs in this post are mine, only the ones near the link : notation with http at the start are links I provided.
1. EVSE upgrade portable 120v/240v EVSE
Upgrade the EVSE that comes with Leaf. Back in the early days this was hands down the best option but with the 2015 EVSE limited again on power and the addition of more L2 chargers in public places this doesn't gain you as much now as it did in the early days.
Max Power : 3.84kW (16a @ 240V for 2011/2012/2015) or 4.8kW (20a @ 240V for 2013/2014)
Upgrade Cost : $287 + Shipping + $25 for the 120V adapter (required if you plan to do any L1 charging) + $37 for a 14-xx adapter (optional)
replacement cost for downgrade : MNL forum/eBay/etc can easily get you a 120V original for $200 or so and you can find people to trade an upgraded one for an original plus cash.
replacement cost for 240V capable version : $200 to $300 for original + $287 + Shipping + $25 for the 120V adapter (required if you plan to do any L1 charging) + $37 for a 14-xx adapter (optional)
Ideally if you have this or are considering this you want a 14-50 jack to plug it into but it will play nice with lower power and other shape jacks if you buy the proper adapter or replace the jack to match the plug you have.

2. Jesla 40 amp portable 120v/240v EVSE
Max Power 9.6kW (40a @ 240V)
Cost : $999
This is the deluxe ultimate road warrior version of the evseupgrade. Better EVSE to start with converted to be friendly with J1772 and adapters equals the top of the line portable EVSE. It's not cheap but it holds the undeniable top spot in the portable EVSE market for those of us not driving a Tesla. Comes with the two adapters you are most likely to use with the option for any other adapter(s) you might need.

3. Open EVSE
Get a kit from an open source hardware design. Buy rest of the items and assemble. Note these can be wall mounted or portable. Waterproof or not. This is the wildcard spot for everything not listed specifically elsewhere in the list that doesn't have a brand name stamped on the package.
Max Power > varies, cost competitive and can be feature rich but often less pleasing to the eye
Cost : ~$500

(just some example pics, there are too many options to cover them all in one URL)
4. Clipper Creek LCS-25P (plug in) / LCS-25 (hard wired)
Max Power 4.8kW (20a @ 240V)
Cost : $485 / $469 plus electrician costs (with plug you pay once and can move the EVSE or upgrade without paying an electrician every time you change something)
If you get a 14-50 jack installed you are a leg up on plugging in your next higher amp EVSE should you get one. If you just need to cheap out the 14-30 jack still lets you use a 14-xx universal plug if you have a evseupgrade and want to plan for possible minor upgrade later.

5. Clipper Creek HCS-40P (plug in) / HCS-40P (hard wired)
Max Power 7.7kW (32a @ 240V)
Cost : $589 / $565 plus electrician costs (with plug you pay once and can move the EVSE or upgrade without paying an electrician every time you change something)
If you had a 14-50 installed previously for another lower amp EVSE this is the max you can upgrade to. You could sell off a cheaper EVSE if you decide to upgrade to this.

6. Schneider Electric EVlink 30 Amp Generation 2.5 Model # EV230WS
Max Power 7.2kW (30a @ 240V)
Cost : $599
White minimalistic look that might remind you of any number of computer products. But it is made by a major player in the home power arena so definitely worth considering if you make it this far down the list. They sell it as hard wired only but depending on codes you might get someone to install it with a 14-50 plug for you.
There are other major corporation made EVSEs but none I've seen that beat the Jesla/evseupgrade routes for portable and the clipper creek / Schneider Electric routes for wall mounted (not counting the Tesla HPWC which is a no brainer for Tesla owners but doesn't exactly play nice with J1772 without modification).
If you want the ultimate in features look in the forums and find an openEVSE maker that will do a custom box for you. It won't save you money but it will give you way more options and you can decide how much information it shows where as some of the corporate options barely have more than a power light.
