Anyone considering a high quality compressor should watch this video by Airgun Advisor. The three compressor topics that seem to be discussed on this forum more than any others are reliability, availibility of parts and service, and value for the cost. This video on the W31 does a great job of answering these questions and providing useful answers to potential buyers. Airgun Advisor doesn't get as many views as paid media influencers but I find his videos to be informative, unbiased, and high quality presentations.

There are a couple of points in the video that I'd like to comment upon. Unless a user is using his/her compressor in a commercial business, the maintenances at 1,000 and 4,000 run hours will never be reached. It would take an individual 5,000 tank top offs at 10 minutes each before reaching the 1,000 hour mark. That is the time it takes a W31 to top off a large 9 liter tank from 3K to 4.5K psi. Second, he is very conservatiove regarding the cost of refills at a dive shop or paintball shop at $7 per trip. Most places charge $10 or more. This doesn't even consider the annual visual inspection fees, 5 year hydro test expense, car gasoline expense, and the value of time spent traveling and waiting for refills A potential buyer should also factor in consideration that in 10 years a used Alkin will have an excellent resale value whereas most inexpensive compressors will be replaced several times over with no resale value.
