The Eclipse will thread itself, but it has tensions. The Imagine threads itself and has no tensions. The Enlighten is much the same as the Imagine but it has dual lighting (better lighting) push button threading (you can put both the upper looper thread in it's port and the lower looper thread in it's port, push the button and both loopers are threaded.) The Imagine you do one at a time and you push a lever. The Enlighten will also do the wave stitch.The Evolution will do all that the Enlighten does and it is also a cover hem machine. This is kinda the Readers Digest version. You can't go wrong with any one of these models, they are the very best. If you want an easy to use machine, get any one of these. Skip the Lauren, you very likely would be frustrated. The Imagine is called the no frustration machine for a reason. If you want to take a little trip....go to Salt Lake City. The prices are better there. Best of Luck.
