We'll be buying a THC in the next few days, but are still trying to decide which one to get. Our table is already up and moving using Mach3 (and we have 2 parallel ports installed - planning to use one for THC and the other for homes, limits, Estop), so we don't need the motor control, just the THC. We already have a floating head installed. The plasma unit is a Hypertherm 1100 with no machine interface - meaning we'll have to use a voltage divider and tap into the torch leads to turn the torch on. The THC choices seem to be:

Proma, from Poland for ~$225
MiniTHC, from Russia ~$270
LCTHC, from CNCelectronics.com ~$275
THC3T-01, from Vietnam ~$145
THC302DX, from CNCelectronics.com ~$525
THC302DVP, from CNCelectronics.com ~$585

Anyone have a recommendation among these? Are there others we should be looking at? Any experience with support (or lack of support) with any of these? Anyone know what you get for the extra $ on the last two?

Thanks!

Doug
