PolyChromeDSP McRocklin Suite has a free trial; it's often on sale for under $100.
It's so good it convinced me to build a computer guitar rig which I use more than all my other gear, combined. I've sold my FM9 MkII Turbo, and my Helix Floor is for sale.
They came out with a few more plugins, and I have one called Nunchuck which is based on JCM800 (stock and modded); another is for high gain, and another for vintage cleans (Fender-ish)
Worth a look. IMO.
I also have several Neural DSP plugins I think are great, Helix Native, Blue Cat Audio Axiom, and Softube Marshall amp room (sounds good, but takes too much work IMO)
All have free trials.
