I am a big Janome fan - but agree for a 5 year old machine $1100.00 is a lot of money. I bought mine new for $1400.00. It came with the plexiglass extension table and lots of feet. The shop also had a deal for the table at half price, and lessons, etc. So I bought another foot (the SID) and the extra bobbin case for FMQ.
Don't know what the life expectancy is for a Janome. So why are they selling it?
Since the Phaff is only a year old, I question why they are selling it also.
Which ever you decide test drive it before you buy - if they won't let you, you won't want it. That is way too much to need to do repairs or service right out the gate.
