I wil be ordering a sytem next week. sold one hobby, computerized christmas display, to expand my wood working hobby. just not enought time in the day. I ahve been looking at the carvewright for a long time and with thesale figured it was time. i will have $1500 to spend including shiping so my thought was to purchse the upgraded traction belts and the one year warranty. what about any other must have bits? also if i do the dust collecter upgrade will it void my warranty since it appears you have to cut the cover. kind of a catch 22 really need better dust collcetion but dont want to void the warranty. thankes for any help
