I am the proud owner of a Pfaff Hobbylock 2.0 serger! I love this little guy; he's just so cute!
I got it for $450 at Button Box Quilt Shop in Wellesley, MA. They also had the Coverlock 4.0 for around $1,400 with the LCD touch screen and coverstitch but I figure it's cheaper to buy a separate coverstitch machine on Amazon or Ebay. (If anyone has any recommendations, let me know!)
Honestly, threading my serger doesn't really faze me. It's not much more complicated than a regular sewing machine, it's just physically harder to get your hands into the machine to thread it.
Actually operating the serger is a little intimidating, but one of the Button Box employees gave me a fabulous two hour lesson and I was serging away like a pro.
I'm very excited about my serger and I've been playing with my new toy non-stop. So much fun!
