My point is for $500 it shouldn't leak, or be expected to leak.

My $350 BAM B50 didn't leak until the cheap Chinese O-rings started to fail at about a year of age.

My $300 ($250 after rebate for prototype review) Xisico 702 doesn't leak... and the gage is pretty accurate too. To be fair I do expect the cheap Chinese O-rings to fail within a year though. When they do I'll tear it down and tune it up like I did the B50.
