Flying clubs in Oakland or Concord?

I just moved up to Berkeley, CA to attend grad school. Before that, I
lived in Silicon Valley and flew out of Palo Alto. I've been flying
with a club there, Sundance, since '99 or so and I've been pretty
happy.

But the drive to KPAO from Berkeley is a bit long. I'm looking to see
if anybody has recommendations for clubs at KOAK or KCCR.

About me: I'm an instrument-rated private pilot, with about 300 hours.
I was working on my commercial rating when I moved. I've got about 15
hours complex time, all of that in a 172RG. For fooling around, I'll
take a 172 or an Archer, and for "trying to get somehwere" I usually
opt for a C182.

I'm looking for a club with a variety of aircraft, low rates, good
maintenance, decent enough avionics to make IFR practical, and
connections w/ good instructors so I might finish my commercial. (which
is admittedly on the back-burner with school on).

Any advice?
