any budget bus compressors/mix glue-r worth a go?

Hiya, I can’t afford any of the awesome stuff like a Portico II MBP or a SSL Fusion so I know it risks being counterproductive, but if there are any budget 100-500$ bus compressors that ppl have enjoyed, id love to try a few budget options. ideally looking for something capable of subtle compression or just adding a bit of mix ‘glue’ to a variety of genres - orchestral, electronic etc.

Thanks so much.
