I'm reasonably happy with mine (East coast, 90 degree humid Augusts, ''89
Westy), despite the fact that on a Westy there are no front vents (unlike on
a passenger Vanagon). Due to the large interior volume of the van (and
perhaps the lack of front vents) it takes a good 10 minutes to significantly
cool the van down on a hot day, so it's not particularly useful for very
short trips, but it's reasonably effective even on very hot days. (In other
words, it reduces the interior temperature to comfortable but not icy
levels.) My prior Westy ('85) had a smaller compressor and vents that were
further back (compressor was enlarged early '86) and therefore it's AC was
slightly less effective (although still acceptable to me). However the
biggest difference I noticed is that with the AC running, my 1.9L '85
noticably lost power going up hills, whereas my 2.1L '89 is less affected by
the additional strain of running the AC.

I don't know why it would hit $600, unless most of it were labor and the
cost of the R134a. All you need is a new receiver/dryer and an R134
conversion kit (o-rings and oil), which are well under $100 combined (at my
prices). Regarding cooling efficiency, I too have heard this, and therefore
opted to wait on converting mine. I have heard that more efficient
alternatives than R134a are becoming available. Perhaps another listmember
knows more about them?
Obligatory plug: I have brand new rear overhead a/c unit sections for
passenger Vanagons for $249 (includes fan, evaporator, etc. but no front
ducting or switches), brand new compressors from $179, receiver/driers for
$59, condensors from $159, and even complete a/c retrofit kits for aircooled
Vanagons. Keep me in mind as spring approaches.
