I have a White Superlock 2000 ATS that I bought through mail-order several years ago. I use it all the time both for clothing construction and have also made quilts with it. I particularly like the rolled hem feature. All in all, I think the true key to sergers is to leave them set up and ready so that you will use them; become familiar with them so that threading becomes second nature; and buy a specialty book to learn techniques instead of just overcast seams.
