Hi, I'm new to sewing, but am jonesing for an embroidery machine. I'm looking on Ebay for a possible good deal. Can anyone tell me what's the difference, or which is better--a Brother SE270D or the 150PE or 180PE? There is a Inovv-is 1000 that is "nearly new" starting at $750. Is that a good deal?

Also, PE stands for Personal Embroidery. Anyone know what does SE stand for?
