I've been using a PICkit3 for several years with no issue. I've also made use of the "code to go" feature to send out updates for the rare occasion where a bootload did not work. I have a couple Real ICE units that refuse to work. One thing on PICkit 3 that caused me frustration for a while is for debug (this is on MPLAB 8), there is not a warning that you have to authorize write to protected boot memory. Instead, it just does not work. I finally noticed that I had to enable writing to boot memory separately. The full chip programming option would not work.
