Shimano CS-HG20-7 comaptible freehubs

So I just got a new Shimano CS-HG20-7 casette and am currently looking for a freehub to fit it on my bike. Unfortunately I wasn't able to find any freehubs that are compatible with it. Can so.eone please tell which freehibs are compatible at a $20-40 budget.

I don't think you are asking the correct question.
Any modern Shimano cassette will fit any modern Shimano/SRAM freehub. Modern being anything in the last 20 years. You will need to use a 4.5 mm shim behind the cassette on a 8/9/10 speed hub.

If you are looking for a freehub to fit a certain hub, that's different. If you are looking for a hub to fit a 126 mm frame, different again.

What wheel set do you have?

If it's any brand of Shimano compatible 8-9-10 speed hub, use a 4.5mm spacer behind the large cog on the cassette and simply install, then reset the RD and cable tension.

If it's an actual Shimano 8-9-10 speed hub, you can also buy a 7 speed HG freehub (although the UG ones seem more plentiful), replace the existing freehub, redish the wheel, and move forward. You may have to add spacers to the axle depending on the width of your dropouts; if they are 130 the 7speed freehub is several mm narrower. Much easier to just use a 4.5mm spacer, however.
