gas proportional counters?

[melissa (M. Woo)]

I'm looking for recommendations on gas proportional counters.  We're
looking for something reliable from a company with good support -- and, of
course, the budget isn't infinite.

I don't want to sound rude (but I will anyway), but I'd like to hear from
users, not from sales reps, please.  :-)  Sales brochures that I receive
often go straight from my mail slot into the nearest waste container.

Thanks in advance, everyone!
