I've had a look around to see if this has been covered anywhere but couldn't locate a thread. If anyone knows of one, please point me in the right direction.

I'm thinking of getting a PDA to start paperless caching. I figure that by the time I buy more printer catridges/paper I could have gotten myself a basic PDA to store all my cache info.

So, in your experience what are the most helpful options to have on a PDA for geocaching? I don't think I would use one for much else.

Where is a good place to buy one?

Thanks for any and all input
