glass is a hard business, and they are pricey most of the time...it really depends on the specific model of vehicle, usually foreign glasses aren't that expensive, at least not on average...but then again the better the vehicle the more options the wins hied has attached means more $$$...
now round about prices my book says that a 2 door 91 civic should go for $280'ish in your area, 4 door is $275...thats without install obviously, and with that you need a urethane kit which you shouldn't give more than $25 for no matter what they tell you, plus $45-72 per hour on glass labor, and its an hour or less job in most cases....
but keep in mind glass is unregulated and competitive, prices may change...
as always, make sure who ever does the work, removes the old urethane before putting on new, otherwise you may have a surprise one day going down the road...
do you not have free glass replacement through your insurance company?
