Portable Sega Genesis

[SuperDoom1]

Spoiler: Why did I make this? Click here to find out!

Hmm...there seems to be a portable variant of all 4th-gen consoles except the Neo-Geo AES...maybe I should combine this idea with a minicade!
Before I do that, though, maybe I should get the portable versions of the others...let's check the prices...
SupaBoy...............................$79.99
TurboExpress.....................$313.20

Okay, now I already know the price of the No---WAIT WHAT THE HELL

There are four portable Genesis-es?! But I don't know which one to get!

From my understanding, there are at least four portable clones of the classic Sega Genesis from 1989:
-Nomad
-GenMobile
-RetroGen
-Retrobit



My question is, which one is the best? I'm looking for one that uses actual Genesis cartridges, has decent sound quality (*cough* AtGames Genesis Classic Game Console *cough*), doesn't run through batteries like a cheetah Sonic on caffeine, and costs less than the NEC TurboExpress.

The Nomad is as close as an official Sega Genesis portable as you could possibly get despite battery concerns.
Genmobile is not worth it unless if you want to get finger cramps (Seriously, that button layout looks horrid.)
RetroGen & Retrobit aren't portable at all. Well, unless you got a Supaboy(SNES portable) plus Retrobit, you could definitely play Sega Genesis games on your Supaboy, at least its it should.

My recomandations is just get a different portable like the Dingoo or the GCW Zero(just be aware of them issues in terms of buttons), those play Sega Genesis games quite well.
