Maxxis or Schwalbe really.

CRC has some Highrollers on sale, though none of the ones I like… Specialized are good but the prices have gone way up recently, you might still find a cheap Clutch or Butcher DH though (Butcher is a Minion-like, Clutch is like a good Highroller)

Schwalbe can be bought for a good price from the german retailers.

I just bought 2x 2.35 super tacky high rollers for 14.99 each from flatoutcycles, they’re second hand but if what they say about the images being the actual products then they look near new. They have some minions on there too for pretty cheap.

Geax Lobo’s for £13 from On One. No personal experience, but online reviews seem reasonably good.

Bontrager Big Earl SSC’s for £15 each from J E James. I’ve used these before, I really like them. Kind of inbetween a Minion and a High Roller.
