Tesla just went on sale, for $10.00 less than what I paid 2 weeks ago...
It's a big mod, and you'll have to get a couple batteries and a charger, so it's a little steeper than the MVP. Both are solidly build units, I wouldn't hesitate to recommend either one. The MVP is more in your price range, and you don't have to buy any extras except for maybe a usb wall-wart, and some juice.
