Third party Jobo tanks on eBay.
Saw a listing for a Jobo-style tank on eBay today.
It's listed as a 2500 tank, and looks like it (see below).
The Seller also has 4x5 reels and tanks, but not Expert series.
There's a thread on Photrio (formally APUG) about Chinese knock-off Jobo products, but this is the first I've seen of tanks/drums.
Wonder what the quality's like? Photos are limited...
