Not knowing what specifically they're looking for in a PDA, I'm going to recommend the Touch. I'm an RN, and when I was looking for a pda, I was looking for something that I could put nursing diagnoses programs, drug books, med calculators, formula calculators (ie: ANC), labwork programs, etc on. I have found that I have been able to put all these programs, plus more, on my Touch for very little cost. I think I've spent $30 total on everything.
