I don't even know what a serger does, so I have no suggestions as to brand. But I do have a suggestion as to where to look. We decided we needed a GPS because age has caused us to get lost easily. (We are in our 60's). So I did an online search. My cusin had suggested a garmin so that is what I looked for. I did not like the prices for these either. When I put Garmin in the search engine, rather than looking at Staples Walmart, Kmart Sears etc, Amazon.com came up. I was very surprised but went there . I found a nice Garmin regular price $320 for $98. This was for a new one. the refurbished ones were more expenisve! So after you decide on brand you might look there. You could get more serger than you thought.
