I use the UAD Studer plugin on each channel on the way in while tracking with electronic instruments and vocals at home, but the usual producer I work with in a band context almost always has the UAD Ampex or the Slate VTM on the mix buss and says he prefers them to the Studer emulation for that particular role.
I’ve also heard particularly great things about the Black Box HG-2 and the Louder Than Liftoff Silver Bullet for your purposes, though that may be more expensive than what you are looking for. The Fatso is pretty legendary for this role as well, and though I haven’t tried it, I’ve heard the UAD plugin emulation is solid if that’s too much cash.
I must also highly recommend the Inward Connections Brute both as a tracking compressor and at the end. Insanely easy to use and sounds amazing. It’s a solid state opto compressor. I have never found a sound I didn’t love with that thing, and there’s a stereo version available now too. I have to imagine with some compression on individual tracks to tame peaks before they go to the Brute to smooth things out that it would function really well for this purpose. When I track vocals, my chain always goes through a FET compressor to tame the peaks, and then through the Brute.
