I love the IDT on Pfaff machines - I'm on my second as I literally wore out the first. My current machine is the Pfaff Quilt Expression 2.0, predecessor to the 3.0 and 4.0. When I bought this machine the thread cutter and knee lift for the foot were brand new and I was leery of them; also the 2.0 was being closed out at 1/2 price - a huge factor on my budget. I'm still not sure I would use the additional features of the 4.0, but I do love my QE2. The IDT is a small foot that retracts when you don't want it (I rarely sew without it), so it is always readily available. It only takes one hand and a second to engage/disengage it. I expect other manufacturers to adopt the IDT when Pfaff's patent expires in 15-20 years.
My machine has never been in the shop and the only problem I've had is a burned out light bulb. I sew on it 6-10 hours nearly every day. I'll be looking for another Pfaff if/when I wear this one out.
