mattdavis11, member and Auto AC technician would suggest to reseal the compressor if you have the skills or money. Cheap fix
I bought my compressor rebuilt from an ebay rebuilder in TX for $240 in '09. Changed the receiver/dryer, all "O" rings, PAG 50 and converted to R134a. Everything fine to date.
You can also get "reconditioned" sniffers on ebay. Usually OK but need new rechargeable batteries and a charger. I think I paid a total of $70 for all parts.
