Which pocket hole jig?

Which pocket hole jig did you use and/or prefer for building your TD that has different wall/galley wall thickness (3/4" and 1/2" ply)? The R4 ($99), the R3 ($40), the Kreg Jig mini ($11) or a different mfg's jig?
The R4, looks like the top of the line, but it may be overkill or possibly cumbersome. I'm not sure if the R3 handles different wall thickness.
Thanks
