I guess I'll go with the wal mart kit since it has the fittings I need and already comes with the oil. I'll pick up an extra bottle of freon also. I hope I don't need to change out the O- rings. If I do, I guess I'll do it after they deteriorate which hopefully won't be too soon

I also thought you had to use the new oil with the new refridgerant. What's the deal with that? Thanks for the input.
