Tri-X is, of course, a legendary film. I like it a lot. But the Foma 100/400 films are wonderful too, if not as flexible in their EI. I really like them in the right developers. That would be my suggestion. At some point, as in right now, 10 rolls of those films will not be such a huge investment. You won't worry about the expense, it frees you to shoot more, and you get to be a better photographer.
Even if I was independently wealthy, I wouldn't pay the prices I'm seeing for a lot of films today. They're not worth it, not when there are other films that can look just as good at a fraction of the price. In fact, the Foma 100 in Rodinal looks more like the Tr-X of old than the current Kodak Tri-X does. So celebrate the price hikes, try something different, these crazy prices are only going to go up, that's a safe bet.
