If you dig into sewing forums, no serger brand inspires loyalty like Baby Lock. Part of the reason for that is Baby Lock's Jet Air threading feature that's available on some serger models, including the Eclipse DX. This feature mainly eliminates the time-consuming manual threading required by cheaper serger sewing machines. Unfortunately, it comes at a high cost. Other than the auto-threading, this is still a basic 2/3/4-thread serger machine that's not all that different from less expensive sergers such as the Brother 1034D Serger (*Est. $225).
Because Baby Lock sergers and sewing machines are sold only through authorized dealers, owners don't have many places to post reviews other than in sewing forums and on some non-retail sites such as PatternReview.com.
This sewing-enthusiast site has reviews dating back to 2002. Furthermore, the user reviews here are generally more detailed and critical than those on other sites. The downside is that site navigation is a pain and in order to see the reviews, you need to register (for free). Still, it's worth digging into the reviews for the Baby Lock Eclipse. In general, owners are totally in love with the Jet Air threading feature and say that the stitch quality is very nice.

There's just one review so far here for the Baby Lock Eclipse DX, but this owner is over the moon when it comes to the serger's Jet Air threading feature.

There are about eight reviews here for various serger models in the Baby Lock Eclipse line. Not all of the reviews are for the versions with the Jet Air threading, but for those that do have the feature, owners can't say enough about it.
