Don,
I read the others comments, I started with ilfsol 3, being really cheap and not being able to buy Rodinal at the time because it was the only thing on the shelf, it's a great developer and being cheap I tried re-using it with tons of success, I could develop about 6 rolls safely, adding only 30 seconds dev time to each new roll. It's supposed to be a 1 shot but I never used it that way and never had an issue. It gets a little grainier on the last two films but the exposure seemed ok.
I now use HC-110 an Rodinal for most everything and DD-X for the REALLY special stuff because let's face it DD-X is awesome for Tgrain and for pushing films.
But ilfsol 3 seems good, and the times listed on the massive dev chart seem relatively accurate. But I agree pushing high speed films isn't recommended, I used ilfsol 3 on p3200 and D3200 and both came out dark at the given times and very grainy.
