My TS 55 died. I need a replacement. What do you recommend ? I have used the TS55 mostly for breaking down sheet stock. It's depth of cut and power were adequate to do a good job. But cutting thicker stock is a real chore for it. I would consider switching models, including battery operated but I have significant track assets (4, 5, and 9 footers) that I do not want to replace. I see there are HK model machines but I know if they are compatible with my tracks. Also TS 75's are currently unavailable. Are they being phased out ?
