B&W Motion Picture Reversal Film Kit - Bellini Foto
Specifically formulated for processing B&W motion picture film. Processes 2 16mm films (30.5m each) or 6 Super 8 films (15m each). For processing Kodak Tri-X and Fomapan R 100.

It can do 300 feet of 8mm film, and quite probably more. I think I'll have to purchase two in order to have enough for Lomo tank processing, but that's still very economical compared to having it done at a lab.
I intend buying from Fotomatica when it comes back in stock there. It's discounted to €20.35 and hopefully the price will stay that low when it comes back in stock.
