I have a PSP I play when we have downtime at work. All I play on it are either classic compilations or emulators, and mostly fighters at that. The cheese grater d-pad is garbage and after putting up with it for years I've given up on being able to "seriously" play fighters on it.

I've been tossing around the idea of buying a bluetooth controller to connect to either my Android phone or tablet for some quick Neo Geo action but I've never used one and know nothing about the different models' quality. Does one with a good d-pad exist? It doesn't have to be Saturn-level quality and won't be taken to EVO or anything, just something responsive and comfortable enough to be worth the price.
