if you live in europe, you can get a psp e1000. otherwise a psp 3000 is probably the best bet. just don't get a psp go, it doesn't have umd disk support anymore so your game won't work on it, since it's for games downloadable off psn only.
psp e1000 is about 100 euro cheaper than the other models (it's about 99 euro or so), but other than missing wifi (which you probably don't need for that type of games anyway) and just 1 speaker (which doesn't matter much since they're very close to each other anyway, and the headphone plug is still good) it's almost the same, other than improved screen and fixed analog sticks the previous models were plagued with.
pro cfw works on it just fine, so you can use that to dump your games in the future.
so, give a psp a try. as you said, the emulator will take months, maybe even years to be perfected to the point most games can be played at around psp level.
