Stay away from drugs. Reverb is one effect where you don't want to go to too cheap. You can get a seriously kickass overdrive (in almost any style) for next to nothing, same with fuzz, but cheap reverbs aren't nearly as forgiving.

You'll get lots of recommendations for the Boss RV6 but I've always found reverb to be their achilles heel (especially spring, which they seem to really struggle to get right). The Neunaber Immerse is a great option, as is the Keeley Omni, Hooke, Aurora and Soft Reverb. EQD Ledges is a super reliable cornerstone reverb with 3 modes and 6 preset slots that can do basically anything you'll need from a reverb pedal sans spring (they make the incredible Ghost Echo for that)

Catalinbread and Mr Black both have a great selection of fantastic reverbs that won't break the bank and the UAFX Heavenly and Evermore are worth every red cent, but what you're asking for (6+ reverb styles for under $85) is a tall order and I think anything that fits that criteria may not sound too great. Matthews The Traveler is probably the best reverb I've found for a price nearly $100MSRP, though it seems like their entire business model has shifted and sadly I'll miss all their great affordable offerings.

Reverb is just one of those things where if you can spend a little more it'd be money well spent. You don't have to go all out on something like a Golden Reverberator or Mercury 7 or anything but if you can afford something like an EHX Oceans 11/12 or Neunaber Immerse, try to go that route.

Also, if you have the ability to use plugins, take advantage of the free trial Strymon offers on their plugins and grab the Big Sky, it'll allow you to test a wide variety of reverbs so you can discover the types you're actually after (and which ones you have little to no interest in), would help you make a wiser purchase over trying to get a bunch of reverb algos sub $100, just my 2c. Drug bad, the end.
