I bought the jxd 7100b, to be honest for the price it's pretty decent. Runs most ps one games fine, mostly use it for ff8 and 9. You do need to install custom rom though before its remotely useable.|
Then there is the fact I had to take it apart, de-solder then re-solder the battery to clear a problem with short battery life. But don't let that put you off!
