are you asking about a serger? (I bought one of those over a year ago & have yet to try using it - major intimindation). For what I do, my basic sewing machine works just fine. Granted have made children size clothing only twice.
I bought this one because it's on the cheaper side and had a lot of good recommendations (including on this board). I know I don't use it to its fullest potential yet -- I pretty much just use the 4-thread overlock stitch for my seams. The only other stitch I've tried is a rolled hem. It works great for my purposes and it's pretty easy to use! I use it on all my knit and woven cotton seams (I love not having to worry about fraying anymore!) and I think it makes my clothes look a little more professional.
I'm very glad I bought it and I think it's worth it!
I have the Juno Janome 3434D serger, I got it last year for $200. My previous experience has been with Bernina sergers so even though this is several steps down, it does the job well. My only complaint with my serger is that the first thread is a pain in the butt to thread without a threading tool. The tool that I have was fairly cheap, like, five bucks and it makes it a lot easier.
