I got mine at litecig usa..but it a type A..but they sell the individual type B atty and
tanks. If you do not mind pink, the starter kit is only $49.99 the additional B atomizers are $10.95. You would also need a package of type B
tanks.$5.95 (and I recommend the spare tank caps for both $2.95). You would then have spare A atty's..or you may even decide you like them..
for me they are fine, I bought this kit because of the price.
I know this suggestion is not exactly what you were looking for...I too was originally looking for a "B". but I really like this vendor and this A kit with additional B atty was economical).
