The PRO-92 & PRO-95 support alpha tagging and programming via computer (freeware), but also do trunking and have no related base models. The PRO-97/PRO-2055 are cheap, easy to find, both use WIN97, and do everything the 1st two models I mentioned do (and more). If you're not in a hurry I know you can find the PRO-97 or PRO-2055 for $100 or less through sales, discounts and other means.
