AllBrands is a Juki Authorized Dealer and Service Center for any repairs including warranty parts and labor. We give unlimited technical support by email, fax and phone. We service machines in our stores. Mass merchants do not have tech service or repair departments for your equipment. They are unable to help you directly, only referring any operational, mechanical or electronic questions back to the manufacturer instead of taking care of problems themselves. Manufacturers and customers should be able to expect that any problems will be taken care of by the dealer or merchant who sold you the equipment, not just by referring your requests back to the manufacturer. John Douthat, Owner & Tech

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.
I've been using the serger since I got it and couldn't be happier with it. It sews great. I called my order in instead of ordering online, and the sales rep was very nice. I'd like to add that I REALLY appreciate the free shipping, and it didn't take too long to get here either. All in all, a happy shopping experience. I'll definitely be keeping you in mind if/when I have to make another purchase for something you sell.
Email representative was quick to respond and answered my questions, item arrived quickly. I'm stoked! Thankyou!
Wow!! what can I say, it was so easy to order, and I was notified as soon as it was sent and my sewing machine came to me all so effortlessly. I was a little concerned at first as we all are when ordering online, but you truly delivered what you stated. You company is great. I will order and come to you first for now on. Thank you so much.

I love my Juki and I am looking forward to learning all the new features soon.
Shaakir and NurMaria,
I think Juki has the best serger. They are so easy to use. I bought a video and the first time I have threaded it, I got it right by following the easy-to-understand video. I recommend their machines to anyone!
