I bought a standard sized one & got a Stealth Mini for a back up very, very quickly. A 3rd one might happen, especially if this v3 they've been hinting at is a VW mod. Otherwise the 2 others on my radar aren't any cheaper - the Semovar & a VV Reo Woodvil. An ePipe would be nice too. I'm just super picky about the woods on the Reo & Pipe.
It's already a given that it won't be VW.
