I used V4L (Vapor 4 Life) pretty much exclusively for 808 batteries for awhile (BTW, I had V2 batteries first and V4L's are much better in so many ways) but I got tired of having to charge constantly because each one (reg size) only lasted an hour or two since I'm a chain vaper

and I haven't found anybody who sells a multi-batt charger that will do 5-6 at a time (V4L really should come up with one of these). Anyway, my next step (2 yrs ago) was to look for an 808 "fat batt" (Ego style) because I had 808 cartos everywhere & didn't want to waste them. I bought one (650 mah?) from CigEasy - an Elegant Easy (no longer available) and another (750 mah?) from LeCig - the PigCig. LeCig has a new version of the PigCig available (now in different colors) but I both emailed & called (left a VM msg) to ask a question and still, over a month later, never received a response.
So I went back to Nhaler, where I bought a bunch of different colored drip tips (to match my flavors in the cartos so I could easily tell which was which - I don't drip) because they have a LOT of 808 threaded stuff. I bought 2 iGo's (that's what they're called there - the 808 Ego Style), one "mini" (400 mah) and a 650 mah and a bunch of the iGo rebuildable Crystal Vision clearomizers. I absolutely LOVE them. The mini is just so darn cute (yes, I'm a little girly). I decided to bump it up and bought an iGo Revolver (EGO style 808 VV) a couple of weeks ago and must admit, this is my favorite of them all.
I've had no problems with the clearos. I bought several of them and dedicate each one to a specific flavor so I can just keep topping them off (no worries about cleaning to change flavor & haven't needed to clean any "gunk" yet even with one coffee juice that's so dark I can't even see through it).
V4L sells tanks and 808 fat batts now too, I just ended up preferring Nhaler (a bit more pricey but worth it for the quality, in my opinion).
I think 808's are still going strong and not necessarily just for newbies. Personally, I'm not interested in a mod or anything that looks weird or way too big in my opinion. They just aren't as common as the 510 Egos. Still, if you go to the right suppliers (V4L and Nhaler are the best IMHO), you'll find everything you need to stick with a modern 808 setup if that's what you like. I do, because I think the 808 has a more consistent & slightly higher voltage - at least in comparison with an Ego, but YMMV.
