I have a seat of BobCad V23 and by the time I paid for the training, tech support and maintenance, I had as much in it as I had in a seat of GibbsCam, and believe me, GibbsCam was a LOT easier to learn and with the purchase, I got free tech support for a year.
I have had my seat of BobCad for 3 years and haven't been able to make a part with it yet.
