Query: Horrible tension!

I learned to rely on reviews only after-the-fact!! This machine is awful!! I bought mine about 2 yrs ago, and it worked ok for about the first year sewing very simple things (pillow cases & such). But after that, it went downhill like it was on a luge! I made the gigantic mistake of not doing enough research before I bought it. It loses it's tension very, very easily. I took it in to be repaired, which cost almost as much as the machine itself. It then worked great - as long as I only used straight stitches. Anything other than a straight stitch on a lightweight fabric will mess the tension up severely!My biggest suggestion for this particular machine, is DON'T BUY IT!! It's just not worth all the trouble!
