The R134a conversion works nicely, but sometimes (more often than not) you will regularly recharge the system. From what I've seen its typically yearly. You may still be able to find R12..but its exhorbitantly expensive per pound that your better off with the R134a conversion.
Personally I would stay away from those. If you dig a bit you'll see each of the replacement freon manufacturer bad mouth the other's stuff. Most of those replacements have flammable contents . If you look at eBay you should be able to find some affordable R-12 for sale. It took me several purchases and over couple of months but I now have enough to fully charge my system (once I get it all repaired).

Re: A/C Recharge
I am confused now. I checked under the hood and saw a label that says the car was converted to R134a, but the valve is still the R12 size. I will have to take it to a shop and let someone look at it. Then I can make a decision on the freon. If it has really been converted then a recharge is not expensive.
If you can, I'd stick with R12...all you have to do is take an online, open book test to obtain a certificate to buy it. I have one, and I buy it, and it works way better than any car I've had with R134a refrigerant.
chazglenn3, My '93 DeVille has the R-12 and I recently needed some added. I went to a recommended shop and he installed a 12 oz can. It was only $20 for the can plus labor. If your car has R-12 I would stay with it, but if it has already been converted you will probably want to stick with it, if it proves to work OK.

awadecki, I have a business account with my local parts store and he said that he couldn't sell it to me without a license. I'm interested in the online test for a certificate that you have mentioned. Would you have a link handy?

Re: A/C Recharge
I changed the compressor in my 91 myself with my 90 parts car, and used an R12 replacement (I forget the name of it), it works just fine, is environmentally safe (no freon), and is even scented and green coloured so you can diagnose leaks. They even say it's colder than the original R12.
I have yet to get around to ordering my R12 replacement things, and as MachX said they are scented, well most that I have seen. So if it does leak into the cabin you will know and can take proper precautions / measures.
