You do a lot of drugs pal? Did a Dingoo eat your baby?
To answer the original question - "Dingoo Vs Gp2x (only For The Next 3 Months)" I'd say go with the Dingoo. If it's just a 3 month stop-gap deal then there's really no contest.
Software wise the GP2x wins easily, however some (GBA, Snes) are better on the Dingoo. The Dingoo doesn't have emulators for a lot of systems that the GP2x has (but people are working on it, apparently) and the Dingoos Megadrive emulator is absolute crap. DIRE. Even DrMD on the GP32 (not saying DrMD is bad, just that it's an old emulator running on an old, weak system) craps all over the Dingoos Megadrive emu.
The things that win it for the Dingoo, for me, is that the Dingoo is actually useable as a gaming device for non-masochists (unlike the GP2x it has controls suitable for gaming), is dirt cheap, comparable/better build quality (come on! the GP2x is a light, cheap, hollow, flimsy feeling thing too!!), far superior battery life, and the emulators are "good enough". Most games run fine and the ones it can't (KoF series is slooooow with sound) aren't playable on the GP2x anyway due to the controls. If Megadrive is important to you then consider a second hand GP32 or a PSP.
I haven't noticed any problems with the screen. Seems better than the ones on my original DS, far better than the one on my original PSP, better than GP2x MKII. I don't really understand the complaints but maybe other people are more sensitive to the apparent problems it has?
Build quality is fine in my opinion. It feels very light, which might be a plus to some people but I find a bit of weight to be reassuring. I guess SoCs are getting smaller and lighter though so what can they do? Put weights in the case?
My main problem with it is that the controls are a little too close to the top edge of the system which makes using the shoulder buttons a bit uncomfortable. This is made worse by the fact that the shoulder buttons are tiny, clicky things. It would be much better if the controls were centered vertically or even a little to the bottom of the system. This may just be personal preference and will depend on how you hold it, how big your hands are, etc. The D-PAD action feels a little soft to me but is still light years ahead of the crap on the GP2x.
If you think that you might end up using it long term then maybe consider a GP2x. As previously stated the software support is much better and it's much more likely to get continued support. Although the controls are garbage maybe you'd learn to love them?
