I have a Babylock Evolve Wave.
It is fanstastic!
I have owned other sergers, but hated threading all of the loopers and remember where the thread had to go.
The Babylock Evolve and other of their models have a patented air threading system where the threading of the loopers are authomatic, A whoosh of air and it is done.
They have a brand new model, Evolution, that just came out, so the Evolve and other models are less now.
Try this one out at your local dealer. You will love it.
I am taking Margaret Tully's class at my dealer in TX in Feb.
If you cannot take her class, I would recommend investing in her DVD.
Have fun!
