The Freon itself, last I checked (last year), was going for somewhere around $65/pound, although the service place I used was measuring it out in ounces, as they should, so in other words I didn't have to pay for some jerk trying to round up to the next full pound on the bill.
I had mine recharged with R12 as I had just installed a new evaporator myself, and the rest of the system was intact and in very good shape, so it seemed like a safe bet and allowed me to keep the car all original. But if you're paying somebody retail repair prices (with labor) to have a new evaporator/condensor/compressor/other component installed, and you're not sure when the next part'* going to fail and leak stuff all out again, I would suggest having the system converted to R134a now.
That way, if disaster strikes and you lose it all, the replacement refrigerant will be cheap, and further down the line, you can do your own routine spring topping-off recharges yourself with over-the-counter R134a kits.
