PSP

I'm thinking about getting a PSP sometime next year after I get some sudden large bills paid and my PC game collection completed. What I really want to know is: is it worth it? I want to play Monster Hunter Freedom Unite and Final Fantasy Tactics, and just those two might make it worth it, but I'd really like to know whether there are any other games that I could get for it. I'm not planning on a fancy new fandangled newfangled PSP Go, either, but probably a used chunky one to cut the cost.
