I haven't had any experience with them, but if one is made with a tach drive on the back and looks right for the TF, I'll probably buy one. I've been interested ever since I first heard about them. I understand they work very well and have all modern components. I would also be interested in one for my antique Ford tractor, which someone converted it to an alternator. The alternator works fine, but looks terrible and very much out of place. PJ
