Greg Dorrance is a great place to buy wood carving supplies and tools , I get a lot from them and they are very quick at shipping your order out , usually the same day. I wouldn't get that set , I would buy the control unit , one replaceable tip hand piece and several tips for it. much cheaper that way. I am sure prices have went up since I bought mine but it was $7 for the replaceable tip and $15 for the fixed tip , the replaceable tip hand piece cost a little more , but you only need one of them for life and it costs less then half for the new tips...
