If it works, then I'd say yes!! You can always clean it up. Or if you want something a bit cleaner, like dave said you can surf ebay and be very patient. Do your research to find out what model is best for you. When it comes to these 'smaller' argons, some do 40mW balls out at 10A, others will do 40mW just barely above an idle. I'd suggest reading through sam's FAQ and find out which is best for you. I kinda 'shot first and asked questions later' when it came to mine, but I got lucky and it turns out the unit I got would be the model I would have been looking for, had I not had the urge to impulse buy ;D
