Hi,
The point I was making was about the price of the board - $6 for three Zif sockets on a pcb as well !
The 2 caps - C1 100nf across Vdd / Vss is a recommended fit to any pic power rails.
C2 across Mclre - assume it must work ok, but it could slow down the Mclre signal rise time - in which case just leave it out - not really needed.
I use C2 on my own boards but as part of the reset switch circutry which is isolated from the programmers Mclre signal by a diode. See Microchips Pickit2 Users Guide for full details of these icsp circuits if interested.
