A ProVari and a Reo are a match made in heaven.

They complement each other very nicely and are both indestructible - I'm talking about the metal Reos here, the Woodvils are not indestructible and are not true mechanicals either (I have both). You may notice that a lot of ProVari owners have Reos for variety.
As noted in my signature, my primary devices are a ProVari with a Rüzgar (similar to a Kayfun) and a Reo with a RM2. I'm all about flavor. Direct dripping was one of my primary vaping methods, which is what led me to bottom-feeders (I also have 2 Phidias). Using a BF is like dripping upside down, the flavor is just as strong, but you don't have to drip all the time, a squonk will do it. If you haven't checked out the Reo forum, you really should, it has a terrific index, so you can find information quickly.
Rob isn't making VV Reos at the moment and I've heard he may not make them again due to having to use 3rd party electronics, but that doesn't concern me - I have ProVaris for my variable voltage and Reos for low-res builds. If it's the price that concerns you, keep an eye on the classifieds, they show up often. I get the feeling that a lot of Reo owners, like ProVari owners, have more than one and sell them to finance other toys, which may include another Reo. Lol!
My one suggestion is if you do decide to get a Reo get an LP model. LP stands for Lower Profile and has a lower cut connection/drip well section which allows for the use of larger attys. There are BF attys on the market and some RBAs can be modded to work as BFs, but many won't work on a regular Reo. Just be aware, Reos can be even more addicting than ProVaris due to so many color combinations and, of course, Woodvils when they are available. Do I sound like a fan grrl? Yep, I am.

I'm the ProVarinati Princess and an Enraptured Reonaut.
Plus, if you don't like it, you can sell it in the classifieds. They hold their value pretty well.
