Hi Props2,
Another vote here for Focusrite interfaces. In the past years I have used many audio interfaces including the Edirol(Roland) and M-Audio. Currently using the Focusrite 18i20 (18 inputs - 20 outputs) The Focusrite Scarlett range starts with just 2 inputs and 2 outputs(stereo) upwards so depending on your recording requirements (how many tracks you wish to record at one time you may be able to work with less channels)
My Focusrite has been very reliable so far and latency is low. Excellent advice above from Guitarhacker.
Having used budget USB mics I would certainly agree that you should spend as much as possible on a good quality conventional all rounder studio condenser mic.
Quality makes look after you when it comes to reliability.
Good luck with your search

Kev.
