I'm by no means an expert, but here's my $0.02.  I've had good luck
with Yellow Jacket gauges.  If you are going to be doing both R12 and
R134a, make sure you get 2 separate gauge setups.  The combo unit is
just asking for cross-contamination.  I have also had excellent
success with the Harbor Freight venturi-style vacuum pumps that run
anywhere from $10 to $16, provided you have a powerful enough air
compressor to run it.  I use a 220v 60 gallon unit which is
fine.  Right now the one with the R134a connector is on sale for
$9.99.  Heck of a lot cheaper than the self-powered stuff, and will
pull more than enough vacuum for A/C work.

Good luck.
