I, too, have a White 2000ATS serger. Love it and have never had any problems with it in 4 years.

I also have a White 2037 sewing machine. I've had it for 5 years and it's my only machine. I've been very pleased with it and think it is a great value. I think I paid $239 at JoAnn's.

I avoid buttonholes whenever possible as it doesn't have 1-step or automatic buttonhole making capabilities. That and pretty decorative stitches are the only things I long for. However, I realize that's big wishing at that price range lol.

And I've never been able to successfully use a double needle in my machine. This could very well be user error, though.
