Well I have been lurking here reading about the trials and tribulations regarding the different small portable compressors, and have come to the conclusion that no matter what you buy, unless you spend a ton of money, it's going to fail, and you will need to repair it. The other option is to purchase a 4 year warranty from Amazon, with the expectation of replacing it over and over again.
It kinda reminds me of back in the early days of the Sony Walkman or equivalents. When you purchased it, anyone with any brains also purchased the extended warranty knowing it was not a matter of if it would crap out, but just how soon. I raised 3 boys, and cannot remember how many of these we exchanged, but I can state with absolute certainty that all of them were replaced repeatedly until the warranty expired. Then you purchased a new one with the extended warranty and started all over again. This cycle continued until the advent of the portable CD player.
I guess this is just something you have to expect going in.
I would have no problems doing repairs, so one of the deciding factors would be the availability of parts.
The air cooled compressors are interesting because it's less messy, but again what about parts?
If you pay around $400.00 for a compressor including a 4 year warranty, you are looking at $100.00 a year to shoot your pcp airguns before needing to buy parts, which doesn't sound too bad.
The reason I bring this up is because until now I have been using a scuba tank to charge both a pistol and an air rifle up to 2000 psi, and getting a lot of charges from it. I have a Maruder 177 coming which runs at 3000psi, and am thinking I could fill it from my scuba tank as full as possible, then topping it off with the compressor. This would be a very light duty for the compressor.
With this in mind what are your thoughts?
