I don't particularly intend the aircraft to be a serious IFR X-C
machine. I intend it be equipped for short-to-medium X-Cs in less than
perfect VFR weather. No hard IMC for me - ever, most likely.

See my soon-to-be post further down for what I'm leaning towards now...

Yup again. That's the difficulty with this whole concept. The 152 is
never going to be a serious IFR cross-country airplane. The only thing
it would be usable for IFR is training. So equip it with the minimum
equipment required. One VOR receiver. Get the static/transponder system
certified. OK, add a glide slope just for training purposes. Anything
more is just putting too much money into an airplane that isn't going
anywhere. IFR GPS is going to be way more expensive than you can justify.
