There's no cheap way to get good quality, just a smart way. It doesn't matter what mic you use it all depends what you know how to do with it. The same ways some people can use regular bookshelf speakers and create amazing mixes; while some ppl with monitors create ugly ones. You can take these claimed 'shitty' usb microphones and record in a good room and have a good engineer do the production. You'll get a DECENT track, you just have to know exactly what your doing. Yes its always better to get better equipment, but if you cant at the moment, learning how to use what you have properly is your last and best choice.
