It's hard to actually buy a bottom feeder. Most are handmade by guys who are doing this as a hobby, so they can usually only handle a few at a time. I understand Fono operates a little differently than, say, Kaji. Whereas Kaji opens up ordering until he hits a manageable mark (say 20 or so a week), Fono seems to build a bunch in advance and then puts them up on his site. Kaji opens sales every Friday (or every other Friday, depending on what's going on in his life to slow down his build progress). I don't know how often, or how regularly, Fono opens up his sales.
Either way, it takes time and dedication to get an order through. Maybe send Fono an email with what you want and he can put you on a list when it's available. I am finally waiting for my Kaji mod to arrive, after a month of waiting. But from everything I've read, the wait is worth it for any of these mods.
In the meantime, you could pick up a Wetbox or a Mr. Puffer to tied you over. The Wetbox isn't great, but it's cheap and it's been a good, temporary PV for me while I wait. The Mr. Puffer has some decent reviews, although it's not a bottom feeder. It's a top feeder, but it accomplishes the same goals as a bottom feeder, to make vaping life easier.
