Good Paid iPad Apps?

[KidZgOtMac]

I only have a few and it's hard to find good ones because if you dont know the name of the app, the iPad app store screws you over. I have some $$$ and I want to get some solid apps. Please recommend all the good paid apps you guys know of, thanks.

These are the only paid apps I own:
Garageband
AirDisplay
Pages
Keynote
Numbers
iCam
iStudiez Pro
iMovie
Infinity Blade
Touch OSC

I have read the reviews about AirDisplay, and they seem pretty bad. The software is very unstable, have you had problems with it?

It's good, I mean, it hasn't really given me any problems. A little lag here and there.
