I bought the small HPDAAV compressor off of amazon earlier this month and it has ran great until this morning. It is leaking on the second stage and will not build pressure past 3000psi. I already contacted amazon and started the return procedure. It only has 2.5 hrs on it so far and should not be having this type of problems. I'm really disappointed and frustrated at this point. It seems like there are not many reliable compressors under 2000 dollars. I love this hobby/sport but I'm about to sell everything off and be done with it. Hopefully my feelings change once I cool down a bit.
