Was holding off from buying one too due to price, had my eye on this one,
https://www.amazon.com/Neewer-Microphone-Isolation-Lightweight-Soundproofing/dp/B01IEZ95GM/ref=sr_1_1?ie=UTF8&qid=1508088821&sr=8-1&keywords=neewer+vocal+boothWell Amazon offered it to me for just over £31, $40 or so, in a lightening deal, usually only lasts a few hours. The company Neewer do make different models of this and different sizes too, this one is the NW6 model, good size too.
Very pleased with it so far, fits well on mic stand, well made everything seems top quality.
Since I have it only a few weeks haven't tried it out yet as regards recording, but have no reason to believe that it won't work. I think these things will dampen the sound reflections a bit but no way will get rid of the lot, so singing inside a duvet may well be the best option for that...lol.
They guy in one of the reviews said its too heavy for most stands but fits fine on my one, and its only a cheapie.But hey it sure looks pro always wanted one.
I think it may have been Mario in a previous thread who pointed me in the direction of this one or something similar, so thanks Mario.
