Bulk loading is fun and you do save $$. I started with the metal snap top canisters, and now use a combination of those metal canisters, plastic screw top and IXMOO. I generally load different film into the different canisters. The metal canisters from Arista are great but they do have a useful life; about 5-10 reloads before they get bent out of shape or too dirty to clean. JUST REMEMBER TO CLEAN THE FELT LAYER WITH TAPE BEFORE EACH RELOAD. Good advice to start with the Arista cannisters to see if you like bulk loading. It make take a couple bulk loads before you get the hang of it, but like developing your own film, once it becomes second nature, you'll wonder why you didn't do it earlier.
The IXMOO are the best because there's no way for the film to get scratched, and generally, once you learn the trick, are the easiest and most fun to load. I load them by hand in a dark closet of changing bag. I have enough for 200' but as you say, they've gotten pricey in the last several years. It comes down to how much film you shoot really. By bulk loading (except TRi-X), you'll save about 40% per roll and multiply that number by the number rolls you shoot a year. That sum should tell you whether IXMOO's are a reasonable investment or not. It's not a sunk cost; you always can sell them too, but prices today are pretty crazy. Just keep your eyes open, and search for leica canisters, leica reload ect. More reasonable deals do appear at times. Be aware, there are two types of Leica reloadable canisters. M cameras take the one with the silver knib.
