Instrument Rating Question

Well I think I am going to finally put in the time and effort to go for my
Instrument Rating this fall but exactly with what aircraft avionics is my
biggest question. Where I fly they have basically all new 172SP's with
G1000's for rent. Obviously this is the aircraft I prefer to rent for VFR
because of all the cool and nice tools they have on board, I like eye candy!
They also have a couple older 172R's (by older I mean 4 years old) but they
have steam gauges only plus Garmin 430 GPS's. I trained on steam gauges for
my private but not sure which way I should go for my instrument. As time
goes I'm sure the glass cockpit aircraft will be more and more common but I
don't know if that is a crutch for learning IFR with or not. Any thoughts?
