So I have used a total of 3 different machines in my endeavors and I just bought a new machine that has blown the other 2 out of the water by far.
It's the Brother CS100t and it has all 5 star reviews on epinions:

I got mine on craiglist brand new in box for 50 bucks which is steal and a half. it has a few automated controls that are soooooo convenient. Sewing with it is smooth and a total breeze and the instruction manual has very good explanations for threading everything and such.
If you can find one online or wherever BUY IT!
