the jobo makes sense if you process color, since the timing is more critical as well as temp control. for b/w, you don't really need it. I do b/w by hand, even at work (deeptank), and use a wing-lynch at work for E6. I've never wanted to do my own E6 at home, but if I had to, I would be looking for a small tube processor. you could do it by hand also, with enough tanks or grads in a water bath, or a phototherm bath, but the processor would kind of limit your exposure to the chemistry, so to me that's a plus.
to be honest though--e6 kits cost about 40-60 bucks or so, and they don't last forever either. the amount of time to prep & set up a small processor, if it doesn't automatically temper & store the chem ready to go (as does a wing lynch or a super sidekick to some degree)--the time for a jobo is longer. so--as far as saving time, that machine (at least for me) is not a good sell, since a Q lab is less than a mile from where I live, and they charge $1.50 a sheet for 4x5.
In my experience with a wing-lynch, you'd be hard pressed to actually save any more money over the Q lab at the end of the day. It is more convenient for a studio though, since you can do a shoot--run your film--and then break the set, without leaving the studio. The downside is in the constant maintenance and tweaking to get the process in control. For my personal work--I prefer to pay someone else to do that.
OTOH--as labs go out of business, and E6 gets harder to find--well, having the ability to do it yourself really pays off. but then, if they quit making the chemistry, well, then the machine maybe doesn't make much sense. plus jobo is out of the darkroom biz now, so you have to think about what sort of parts & support are available. I don't think buying new, makes any sense now. buying used is tricky though, moreso with the automatic machines, unless you have some experience with the model--because you can get burned.
and no this isn't doom & gloom. I've been working since thanksgiving trying to fix an ilford paper processor, with limited parts & support available, even though we can still buy paper & chemistry. alot of money in the hole basically, trying to keep it running--you have to think about the budgets--you just have to. I'm not talking an old porsche or anything, but when you have a couple of thousand bucks worth of materials going stale, while a machine is down for lack of a part--because the photofinishing industry is tanking, or has tanked--well--makes you long for the old days when we did it by hand. if you keep your process simple, you'll be happier...
so, that's my 2 cents. hard to beat something as simple as hand processing.
