Mine is an earlier version of this one from Argos

It's fairly basic but does do quite a lot of stitches.
Loz got a new one, I can't find the thread now, I think it's a Singer.
Generally I feel the more electronic things are, the more there is to go wrong
Mine doesn't do automatic buttonholes, but I don't know how easy they are as I haven't done any
It can have several different feet (foots?!) and they're very easy to change.
I've found it ever so easy to use, and the instruction booklet is very good too.
Haven't made anything very clever, but have used it on really thick denim for instance (Minnie's toys) and it manages that fine.
If you have a local Singer shop though, I'd go there and talk to them. I didn't know when I got mine, there's one in the next town.
