I dont rec. people use over the counter a/c recharging equipment, its basically propane which is explosive....most of the kits don't include dye... so you would have to check everything with a soap solution....Redtek does work good, however if you have to take it in to a dealer they are going to charge you big time because you can't recover redtek with a r134 based machine, it makes an azotrope out of the 2 refrigerants and it is very expensive to dispose of. But yes there are cheaper alternatives.
