I just bought and installed Juicebox Pro 40 last week after paying my electrician to install a 14-50 plug in the garage. They have a $50 off coupon if you go thru a Plugshare page, and they didn't charge tax or shipping so it was $549 delivered.
I was close to buying a GE Wattstation for $399, but in the end I knew I'd want a WiFi unit so I could get data to analyse usage. I'm glad I did, I don't think I would want to charge blind, I'm kinda nerdy like that. The app could use work, it is very basic and I hope they make it better, but it gets me enough info for now.

BTW, if you rent your Palm Desert house out in the off-season let us know, a vacation rental with a Juicebox, sign me up.
