My first two were old fridges with a hole in the door for the faucet. Functional but not pretty.
The next one was a Beverage Aire commercial for around $1000. That was pushing 20 years ago though. After it finally died the compressor was no linger available to fix it and my friend that worked for an appliance repair said their compressor guru tried a universal one in a kegorator and was not happy how it worked.
The latest one is a Nostalgia Electrics. Not the most fancy one out there. The tower was really cheap but I planned to replace it with the triple tower from the last one. So far so good and I only paid $300 and something for it. It arrived with a ding in the left side so I called the supplier and he said filing a damage claim will be a huge PIA, would you be OK with $50 off. Well since that side was not going to be in view and it would be easy to fix it up anyway, I said you bet.
It also came with a really cheap regulator. Again no problem since I already had two so that one became emergency back up.
The front of them is round almost like they just added an extended door to a small fridge. If you are trying to put it under a bar so it fits flush, it may not workout. The drip tray is just a flat plastic piece with a SS grate. I usually have a plastic cup or something under the tap in use so that's no issue. Way easier to just toss the cup than wash the tray.
So it has been going for a few years now. Almost enough to call it good for the price if it craps out.
One last thing. It makes some odd noises but is very quiet. Google Nostalgia Electrics kegorator and take a look at the price. Still in the 300s.
I do have to say that the Kegco cabinet only is a great option for someone replacing a defunct unit and still has everything else.
