If you like the features of the V10, I'd suggest a used V20 (unless you are lucky enough to find a new one). LG fixed the bootloop issues, so that isn't a concern with it. It's also still the best total package in my opinion, even over the V30. The V30 took away multiple features, and is just an otherwise minor spec bump over the V20. My V20 from the initial release still runs like a champ.
For what it's worth, I'm kind of in the same boat. The V30 would be a downgrade for me, and their designs are moving to imitate SamApple. I have no plans to get the V40 either, unless they come out with something killer that I can't do without (which isn't likely).Thanks I'll check out the v20 then... I'm just not sure how I feel about LG right now
