I shoot, develop and scan 120 b&w film, but only a few times a year. I use Ilford HP5 film, Kodak HC-110 developer, a water stop bath, and Ilford Rapid Fixer. I use a Patterson developing tank, which seems to me the easiest to load. The HC-110 I use was purchased at least five years ago, is highly concentrated (I use 10ml diluted in 17oz of water per roll) and has a pretty much unlimited shelf life, but I understand the formula was changed a couple of years ago, and I don't know how it compares to what I'm using. The fixer, on the other hand, has a fairly short shelf life, and I end up having to discard a lot of it, wasting money.
My scanner is an Epson Perfection 3200 Photo, at least 15 years old. I use Silverfast scanning software. I experimented quite a bit using tape to shim the negative holder up off the scanner glass to more or less focus it, and found that three layers of tape gave me the clearest scans. A newer scanner would probably be easier to work with. I process the scans using Photoshop and Lightroom, and have gotten some results I'm really happy with. My cameras produce 6x6 and 6x9 negatives, and I've made really nice 12 x 16 prints from them. By the way, if you've not done this before, you'll probably be horrified at how bad you scans look compared to digital images, but you just have to process them as best you can and see how they look under normal viewing conditions (in my case prints), which have often been much better than I would have thought.
As I said I do this fairly infrequently, and while I've developed a workflow that (usually) works for me, I still go at it somewhat blindly - every time I do it it seems like I'm still experimenting.
I have also used a lab (thedarkroom.com) with good results, and in fact am considering doing this in the future rather than processing myself. Considering the frequency I do this it may actually be cheaper, and the scans seem a bit better than I can do at home.
A good resource for you would be the forum on photrio.com. Hope this helps.
