I find stock 4.2.2 too fluid and functional to dare try anything else for a while. I do miss the options of other ROMs but with a phone this fast the temptation to mess with it is less

I had this problem but have now installed the game. I was already on Simplicity ROM and had the Semaphore kernel installed, this has an add on that allows virtual 50Mb cache. This didn't help in the Market though.
I had to go to their own website...
