I have an Ace 250 that I have been using for about 2 years. It is in very good condition, works well and comes with the stock coil, the 4,5 inch sniper coil with extra lower arm and the 9x12 inch coil. The stock coil and sniper coil both have covers. So . . . the Ace 250 with three coils. I would like to know what this might be worth. I feel the itch to get another machine but would need to sell the Ace to upgrade.
