i'd also extend the tbone's comment with make sure you get a legit pickit 3, you can never be too sure if the clone will support thesame pics, even as new ones come out. plus, even if a new one comes out, i'm sure the pickit3 will support it fairly quickly, as opposed to a clone, might take awhile for the designer to realize it's out there, add the suppport, test it, etc...
that's even if they bother with the particular clone you're on, or make you buy a new one.
