Check out epipemods or the Jazz carto pipe (but you can toss a clearo on it too). They're pricey as all hell though.
A slightly cheaper option is to grab a Kuwako from Janty to toss on an eGo-sized battery. Not exactly the same though, but if yyou want it in automatic it's virtually your only option.
There's also the 601-C. It's an automatic carto-pipe, but it's 510
threaded so you could at least
throw a Nano on there if notthing else.
