Yup. I bought, borrowed, traded for, and/or tried it all for a couple of years. Then... I bought a couple of REOs. After that, I didn't buy anything but juice, attys, and occasional replacement batteries for more than 2 years. When I finally did succumb to my desire for something new, I bought another REO and a couple of Reomizers. I didn't need them - and I wasn't looking for something because what I had wasn't good enough. I bought out of desire, not necessity.
There is no such thing as an "upgrade" from my 2 1/2 year old Reo VV Woodville. I really love my new SL Grand, but it isn't an "upgrade". -- I'll add that no "upgrade" exists for the SL Grand either. There isn't anything better than that on the market. I just wanted it because it looks cool.
However, these RM2's and RM3s are pretty impressive compared to my favorite commercial attys. In fact, I can't believe my standards used to be so low when I compare the flavor and vapor production of the RM2 or RM3 to the hh.357 and i06's and Aeros I stuck with for so long. -- That was a happy accident. If I would have never tried an RM2, I would have never felt dissatisfied with the hh.357 or i06 or aero. I'd have never known nor cared what I was missing. I was quite satisfied with any of those or even a good 'ol cisco 306 when availability was an issue for my favorites (often). Now, I'll never buy another commercial atty. I feel a little bad since Iken and Avid treated me very well for so very long...
Maybe another 2 1/2 years will pass before something strikes my fancy again. Maybe nothing ever will. Don't know. Don't care. What I do know is that what I have works great.
