Which is the best type of serger to buy?
It all depends on how you would use a serger.
If you would only overcast single layers to keep them from raveling, a 3 thread serger would do like Juki MO623: http://www.sewingmachinestore.com/products/abp02533.html
If you seam knits, a 4 thread mock safety stitch is best Like Juki 654DE:
If you seam wovens, the best stitch is a 5 thread safety stitch like Juki 655:
Most all sergers do roll hems and differential feed, so the difference is how many threads you might use.
Some sergers even have the coverhem stitch with 2 or 3 straight stitches on top and a serger stitch on bottom. Juki has the best of all in the new MO735.
