We've had the IVT in our JD's for a few  yrs now. I do not ever see us returning to PS, though we have PS in the 4wd. Personally, I wish IVT was available in the 4wd type tractors as an option also. We've not had any trouble in a few yrs w/the IVT. Intially, there were a couple of quickly remedied settings that needed to be fixed by the dealer. Took the tech about 10 minutes w/a laptop & all was fine. No wrenches needed. We use our IVTs for tillage, planting, sidedressing, grain cart, etc. No stationary pto work for these tractors. Learning to operate them really only takes a few minutes. Showing someone how to "dial in" the speed they want is about the only instruction. When working with the I-Tech Pro (fka IMS), the IVT makes it much easier to set up. If you're not planning on Itech, then it's still easier to turn w/IVT....we think.
