The incredible EXPLODING sewing machine!

So I posted earlier how excited I was to get a good deal on a sewing machine for my birthday. It finally came on Saturday, with a big box of needles and other goodies and a pamphlet straight out of the 70s. The sewing machine was rather simple; none of the fancy stitches that the one I use in my course has. But it was easy to use and I want something basic to start out with anyhow. If the sewing thing really takes off, then I will invest in a fancier machine. Anyway, I used it for about 5 minutes, trying out the different stitches and was having a grand old time. The motor sounded kind of loud, but it's an older machine I figured. But then my baby started crying and I had to go lay her down. When I did, I heard a POP POP POP. "What the was that?" My husband shouted from the other room. We both rushed into the living room to see a smoking sewing machine that had exploded. Anyway, that was pretty much a killer for the rest of my Saturday, anger, disappointment, etc. I tried to contact the seller but she didn't answer. I was tempted to give her a bad review (I mean, there is no guarantee on ebay but you DO expect the products to work longer than 5 minutes!!)but thought I'd wait until Monday. Today she finally wrote, very apologetic and offered to give me half of the money back which should hopefully be enough to get it fixed so fair enough. Anyway, I'll keep you posted on any further explosions or eruptions and there consequences!
