How awesome of regs do you really need? I have a couple Sherwood first stages I bought used for $50 each, and I can't tell the difference between them and a Mk17.
For recreational diver asking about DIR like the OP, this can often mean getting another matching first stage for doubles, getting DIN regs, getting a true backup second stage instead of a compact octo or Air2, or getting regs that have better hose routing for doubles. I didn't see it as meaning "more expensive" regulators (heck, those $60 TDS regs might be perfect).
