To OP: All the advice and suggestions here are good. I might change the suggested one-shot developer from HC110 to Rodinal. Both work great, I just find that the Rodinal will store for a longer time. I have Rodinal that was opened 20 years ago that still develops film. I don't recommend using such old chems of course, but it just shows how Rodinal will remain usable over long term. Rodinal stored sensibly will easily last you 6months, likely longer. Depending on how many rolls of film you develop, that could be an advantage.
I develop between 2-8 rolls a month. I mostly use Rodinal 1:50 for my usual developing (unless I'm specifically attempting a fine-grain film, etc.). My 1/2 liter (500ml) bottle of Rodinal will easily last me all year, and beyond. I store all photo chemicals in a cool location that is completely (or nearly) dark, don't leave the caps off bottles longer than necessary, etc.
One more thing. People everywhere (in US) are divesting themselves of their darkrooms now that digital has captured the average photo enthusiast. As a consequence, I see darkroom and film developing equipment piling up in local thrift and secondhand stores. I have 3 such stores in my town and they all have developing tanks+reels available for very little expense. Well, 1 of the thrift stores in town is oddly very expensive and often prices things above what they cost new. I point it out and they just look at me. Frustrating when its something I have an interest in.
Developing your own film at home is rewarding. I don't know what your experience level is, but if you have problems with the first few rolls, don't give up. I found that once I settled on the work-flow that worked best for me, I could achieve consistently good results with minimal effort and mess. Good luck and enjoy.
