The only chart I'm familiar with is
THIS ONE that I copied over from the old yahoo website a few month ago. I don't know who originally compiled it, nor do I have the time or inclination to maintain it, so it may be somewhat out-of-date, but as far as I know, it's the best we've got out there right now. I think one of the vendors (check the marketplace section) has a link to a similar chart on his site, but I don't know if that's kept updated, either.
For example, it does not list the HTPro (URC 9910 clone), the URC 9962 Kameleon (a 9960-clone with RF/IR blaster), nor the URC 9690 (half Kameleon, half-hard-button) that I believe are all JP1.
Also to my knowledge, there are precious few (if any) real JP1 remotes being manufactured out there any more, as UEI has gone over to the "dark side" of JP1.2 and Flash ROMs, so the only likely place to find these are using the vendors advertising here (I recommend our very own Robman for price, availability and service) or on eBay.
Good luck.
