I have a BL Decorator's Choice and I love it. I had to travel to another city to buy it, so I only got a 1 hour lesson, then I was on my own. The manual is great and the machine easy enough that I have had no problem using it.
Here's something I go by.....if there are a lot of some machines on ebay I assume that folks don't like them....few on ebay and folks hold on to them or sell to their friends. I have not checked lately, but last I did there were few Babylock's on ebay.
