1. KeDei 3.5" touch screen


Avoid!! This screen has a terrible refresh rate and is unsuitable for any gaming. The image took a day to download from their website.
It is a cheap screen for a reason!
2. 2.8" Touch screen (ebay $14.50/£10/€12.80...http://www.ebay.co.uk/itm/291335549448)
This one is similar to the adafruit one:

So I tried it with a cupcade image and it booted right up, in 10 minutes after receiving the parcel I was playing!!

It's good, I will be keeping this for now and maybe connecting a zero up to it. It is a smaller screen with potential.
