I've had a Gammill for 12 years and I absolutely love it. I do all the maintenance myself (they have great videos on their website) and have never had a service call. I've called tech support twice but the problems were easy to solve (one was operator error). Gammills are pricey but they are made to last. Mine is not computerized (I really love ruler and custom work) so I can't speak to that. I have friends who have bought used Gammills and love them too.
