Convert to R134. I have stock components running on R134. Pretty darn cold too. To convert just change all seals, orfice tube, accumulator, and possibly the hoses. Take off the compressor to drain out all the oil too. Preferably just change the compressor when you convert. I have a $99 compressor and it's been running fine for two years now. I changed the hoses because the stock ones tend to leak over time. The new style of hoses have a plastic barrier between the outter and inner sides. This helps keep the freon under pressure and helps slow down permiation. If you change hoses run them together over the engine instead of over the fan guard.

Dan,
Any A/C compressor repair shop can make hoses for you. I had mine made for about $100. By routing over the fan guard look at this setup. A simple R134 conversion kit at the parts store has the O-rings and oil you need. I believe they are green o-rings. The orfice tube is over the counter parts too. The accumulator cost anywhere from $40-$100 according to www.carparts.com. I would definately replace the accumulator since any shavings or dirt collects at this point. Once the system is rebuilt, a professional should pull vacuum on it for at least 15 minutes to check for leaks. Once it passes charge it up with R134.
