I have a super-clean Devo 7e with Deviation 5.0 installed, and no other mods. Comes with original box and no batteries.
It's clean and un-modded inside. I have had the back off about 5 times, each time thinking I was going to either move the USB port to the back, or investigating how to do any number of hardware mods, just to realize (again) that I have no soldering skilz.
Selling for $45 net to me (you pay shipping from 96003 and pay pal fees),
