Sandy, the digikey catalog usually has a good chart that lists how many
uarts, a/ds, io lines, etc. each PIC part has.

Digikey also sells two cheapo programming kits.  Stay away from them,
and get the picstart-plus kit instead.  The cheapo ones are only for a
few specific PICs, and the software is ancient.  The new picstart
software is great, but it won't talk to the cheapo programmers.  I
started a project a while back with a PIC, first real hardware project
ever, and was really surprised at how well it all worked.  I'm sold on
PICs.
