I'd second Imi with perhaps not getting a combined machine, unless you are very short of space, although as this machine is now discontinued, maybe if you are getting it for a very good price...
It only took me just over a year to realise I wanted a bigger embroidery area than 7" x 5", and thus buying my Brother V3. But they are the price of a second hand car, which is ridiculous really... but much more fun of course
