Prompt [Q] Need to re-image Chinese Android phone

Hello,

I need help doing a fresh install on my android phone. It is a Chinese Android phone called Mega Droid purchased from chinavasion.com. As I do with computers I have installed stuff, removed stuff, gained root access and generally made a bit of a mess of my phone. I feel I need to do a complete re-install of the Android image. Herein lies the problem. I have no idea what Rom I could install with no issues both stock or custom? My phones details are:

Model Number: 11_gq2000s_fwvga
Android version: 4.2.1
Baseband version: MOLY.WR8.W1248.MD.WG.MP.V6.P4,2013/05/08 18:36
Kernel version: 3.4.5 root@android #6 Thu Jun 13 17:41:18 CST 2013
Build number: 11gp2000s_fwvga_20130606.

If there is anything further you need please ask.

Cheers
