The RM2 and RM3 are great little atty's, what I started with, still have 7-8 of them, 3 of them still in service with enlarged air intakes on Mini Woodvil's and the VVG. The Cyclones were a step up, the Chalice atty's are a step up from them in quality. I like my Chalice II (that I paid way more for than the Chalice III's), but it's not liked as much as the Chalice III's because of their air flow that works better for my long lung hits and require less slipstreaming than I have to do with the Chalice II. If I could get to my drill press in storage, I'd drill the C II out. Best small atty's for my LLH's are still the Cyclones... because both were bought used and both came with monster air intakes already drilled out. But all of them can produce massive flavor rich vapor, and they all easily do it better than any of my 22mm atty's. The Nuppin's bridge the gap as my only mid size atty's I truly like (unlike many that like the RM4 I don't like my Atomic much). I get plenty of flavor rich vapor out of them. The RM2's & RM3's are easily worth what they cost, so were the Cyclones to me, but so are the Chalice atty's now. So there are great atty's available for every budget. Truth be known, I like my small footprint atty's better than all those that are larger. Many of the larger I have I don't use at all because of that fact, or they are constant leakers or because they can't even come close to delivering the flavor I want. YMMV
