There are a lot of good ones from many makers. But best bet for free plug in and play profiles would be MBritt. He and many others have free sample packs with several amps available for download on the Kemper website.
I have one of Matt's profile packs (1959RR) and it's great. I don't have more as we have a lot of the same amps. But I am definitely getting his "Camerica" profile when its available!

Tons of great ones from a commercial perspective (MBritt, Choptones, SinMix, Mattfig, Guido, etc). Tones of great free ones on the Rig Exchange. Lots of free packs on the Kemper website too from some of these very commercial profilers.
For free ones, djemass's Mark 2c+ are the best high gain ones on the rig exchange, and there are some good hiwatt and trainwreck (certiatone SSS SRV profile is great) profiles on there too. The best high gain profiles for purchase I've found are Pete's. http://petesprofiles.weebly.com/
I've been happy enough that I haven't bothered looking for new ones for a while! Cheers
