buying recording equipment

Hello, I am an aspiring audio engineer that has been mixing & recording for about 6 months. I only do Rap/Hip hop , I've been wanting to upgrade my current setup to something better. I currently own a Bluebird spark SL & a cheap $99 M-Audio interface. I want a little more of a professional, cleaner, & overall better sound, So I decided to create a interface chain instead of purchasing an interface alone. To start my chain I've decided to pick the Audio-Technica 4050 Microphone, because of the great reviews especially for rap vocals.

How it going everyone? I’m new to the site and new to the subject as well...for a long time I’ve wanted to buy some monitors and get into mixing my own music and I wanted to create an album. I never went thourgh with it because I couldn’t afford it. I’m a little older now and can afford to buy the equipment of a studio and sound proof and treat a spare room I have. Thanks to the power of credit lol. Anyway this is a dream ive had for a long time and I don’t want to keep waiting to start practing mixing and recording vocals.

i'm going to buy a preamp. a cheap one i might add.

so i'm going to choose between these:

studio projects vtb-1 (118€)
art tube mp studio (59€)
art tube mp studio v3 (88€)
samson c-valve (109€)
PreSonus tubepre (111€)
nobles premaster (instrument preamp) (68,50€)
sm pro audio tb101 (111€)
sm pro audio tb202 (155€)
and, yes, Behringer mic200 (59€)
(sorry for using the "b"ad word)

i know they're not the real thing, but i can't and won't spend more on it.

Hey,
Anyone have any regrets on studio equipment bought?
Ever bought something you've sold the next day and thought "not buying that crap again!" ?

(Feel free to mention Behringer equipment, just don't talk about "Behringer " itself being crap or not, thats not the point of the excersise)
