Haha yeah sadly I have and yes they are dreamy and I can't think of an honest legitimate negative thing about them and yes as a DST owner you always get "spin envy" from your buddy with the MK25 that just sits there smiling at you as he spins his LP hoses around and around and around.
I started with Apeks and have been using Apeks regs for so long with no issues I put alot of trust in them especially as BO regs for deep dives and I have soooooo many of them (think I have 6 DST's, 2 DS4's and 4 US4's) and so many spare pats and rebuild kits etc I just kind of have fallen in love with them and now its way to hard to transition to SP anyway. It reminds me of camera bodies once you get about 4-5 Canon L series lenses deep your kind stuck and its a mission to switch over to Nikon
