Can we talk?! (That was my Joan Rivers impersonation.) My quick search of cover stitch machines has revealed 3 contenders. This is the Babylock - I believe Robbie mentioned this one. It may come in a combo machine with special jet air threading if I remember correctly. Otherwise I don't know anything about it.
This one is Becky's machine that I played with at GCGSW - I think this is the same model. Katie from Kadiddlehopper has this one too and gives it rave reviews.
And this is the Janome. Looks like my other little Janome pretty much. I think my local dealer, All About Sewing, sells Janomes, so I might could get it locally.
So, what I've heard from the comments so far are that the combo cover/serger machines are a bit of a pain to switch over, and it's nice to have a stand alone if possible. I have my mom's old Riccar serger which is working fine, so I have no need for a combo machine. But what brands do all you ladies use, and what advice do you have? Also, where did you buy them from? I'm listening....(That was my Frasier Crane impression - I'm going to change my name to Rich Little!)
