As far as I can remember, JOBO has filed for bankruptcy in March this year. It is still possible to buy JOBO tanks in Germany, but I suspect that that's just remaining stock.
So, you will probably still find used JOBO tanks on Ebay, but if you want to buy new equipment, try Paterson. I am quite happy with Paterson tanks, and I use spools by the Spanish manufacturer AP. These spools are made of plastic, and their design allows for very easy, foolproof film loading. Plus, these spools are fairly inexpensive, so I use two sets of spools for my tank, allowing me to process larger numbers of film because I have one pair of spools in reserve.
If you want to use a processor for film development, then you might still have to use JOBO. Phototec in Germany still sells JOBO tanks as well as Heiland film processors designed for JOBO tanks.
