PDA suggestions?

[siccjay]

I need one of these badly. I buy and sell CDs, so I would like to be able to lookup certain CDs online or at least keep track of what the store has so I can come back and buy the good stuff.

I need a good PDA, nothing really fancy. As everyone, I'd like the best for my money.

Whats the deal with these connecting to the internet? Is browsing fairly normally on them possible? Monthly fee?
