Mine is still working like a charm. The ice bank control on mine is gone too, never worked since I had it so I have a timer on the outlet that turns it on either 30-45 mins a day depending on the season, doesn't over freeze, and always keeps it cool.
The taps do stick if not used for a bit, but so will most taps except perls. I tweak the pressure on the kegs a bit due to fluctuations in my basement temperatures, but it's just tweaking to get the carb and serving pressures right.
I still love mine, and for me was the easiest way to get into having my beer on tap! Easy to check the levels of beer in the kegs too since they are just sitting there not inside the freezer or fridge.
