New member here. So cheep I squeak. I didn't like payin' $100+ for anything as rudimentary as catch can. I was considering very seriously about making my own like so many others suggested from Lowe's air compressor parts, etc. Several reviews I found discuss the faults of various compressor filters--build quality being the main complaint--leaks, cracked housings after extended use, etc.
I was leaning towards the Elite Engineering can despite the price, for its' absolute quality. I have one, but didn't wanna pay that price again. . (Hindsight, experience, and a "painful" fleecing has taught me that a catch can is a catch can is a catch can...so long as it's durable, flows well, and has no build fault for leakage.)
Extensive Googling of catch can reviews brought me to this:

$59 no shipping charges. It seem to garner very good reviews with no negatives that I could find. No sight glass, but it does have a dipstick. I was leery about the clear tube in most of the catch can versions I found; and I'm not a big fan of eBay "sent from Hong Kong". Even the Mishimoto has a poor Amazon review for leaks around the gauge.
$59's only 20 something (and no tax) more than a Lowe's fabrication, and all metal, it should be sturdier.
