I see that only certain colors are on sale for $150 - pink, green, tan, and tiffany. A substantial discount if you want one of those colors, for sure.
Having said that, I owned one of their Comp 22 RDAs and it was a leaking machine. NOT from the air inlets - mine leaked from the o-ring seal between the deck and cap. I let it sit for a while (unused) with the air inlets closed and it still leaked, so I returned it (purchased locally).
