my mother actually bought some dishes and they came with this real heavy duty foam. she saved it for me instead of throwing it out, and i was going to make one of mic curtains or whatever you want to call it with that foam stuff, and a music stand i had. however i ended up using the foam to build an enclosure for my amp cab so i can get a punchy dry sound. it works great for those arena guitars.
anyway, if you got the money to toss around, itll prob help a great deal especially if you are in a square garage or something with flat concrete walls. but you can make one for a lot less than $200. even if you spend $100 (which is still ridiculous) u still only spent half of what you would have to buy it.
also, for anyone that doesnt have a pop filter, idk what those are going for nowadays, but an old pair of stockings over a bent wire coathanger works great. and its basically free. (i have girls in my house so i find the weirdest girly shit that seems to sub in perfectly for other expensive recording shit.)
