We're using an older version of Bobcad here, mostly because we got tired of paying through the nose for upgrades... How much did your seat cost you?
(fwiw, we're feeding a Shizuoka AN-S through an Allen-Bradley 8400MP with the system, and it works fine for a lot of what we've been doing - I'd eventually like to go with a PC-based control system, but right now, if it ain't broke, it ain't gonna get fixed)
I made the mistake of calling BobCAD about 8 years ago. I get a phone call from them at least every other month. SolidCAM 2.5D with the seat of SolidWorks set us back about $7k. We're running 8 Fanuc Robodrills, 2 Kitamura 1xiF's, a Hyundai Kia lathe and a Fadal EMC. Fanuc controllers 16iMB's (IIRC) on everything but the Fadal. SolidCAM has the update plan, but it is on a descending scale. After about 4 years, you are paying 30% less than you do for the initial subscription.
Gibbs doesn't do that. We have 3 seats of Gibbs, and one with full 3D surfacing and lathe. I forget what the subcription fee is, but if we don't get it our boxes are unable to read the latest version of the SolidWorks engine. They have us by the short hairs, and they know it.
Most of my customers are using SW. A few use ProE, but since we are a subcontractor to subcontractors, I don't usually get those files, just prints.
