After 35 kegs and nearly 3 years with this kegerator there are very few parts left over from my original kit besides the tower and fridge. The co2 regulator and co2 line were from the original kit and started to show their age. The regulator never seemed to show the accurate tank pressure and just lost the ability to regulate pressure properly. Adjusting it was always hit or miss. I picked up a Taprite T742 and a new co2 line. It is awesome. First of all the tank pressure reads properly. Secondly, setting the pressure was easy and seemed to be very accurate. The adjustment dial is great, the unit is overall more compact, and the gauges are better quality. It’s a great investment.
