Reasonable on 17 October 2009
I'd suggest you download every demo you can get your hands on and see what suits. Pretty much every major PS3 title has a demo now, including LBP.
I'd also look at PSN titles like Flower, Wipeout HD, etc.
I can't advise more than that as I love Uncharted, etc. so clearly my tastes would be useless for you.
If you want to get access to even more demos, make accounts for other regions as well.
Try to be reasonable... its easier than you think...
