Need Info on Serger

Well, I do believe the serger I bought used, @15 years ago, has gone to it's final resting ground. The women at the quilt shop where I go for repairs were kind enough to let me borrow a "very nice one" to finish up my pillow cases. I like having a serger but don't use it very often so don't really want to spend the BIG $$$$$ on a fancy one.

I'm happy with just 2 needles. Would like one a bit easier to thread than my old Kenmore.

So, does anyone have any recommendations????
