This plugin is sort of a niche product, but could be the best sounding plugin available as far as hardware modelling. Its similar to a convolution reverb, but uses impulse responses from all sorts of hardware. The demos I've heard are quite impressive.

This is a new set of compressors I've made for Nebula. Nebula compressors have had a reputation for not really being too reliable for their compression abilities, and many people just use them for their tone and use a separate VST for compression. I think this set of comps should change that. They are based on very transparent hardware but the results still sound like analog compression.
