I agree on trying to sell them on your own first. I have a Janome MC4900QC and I was not able to sell it on my own or trade it in for anything near what I paid for it - and I got a really, really good deal on it. I'm going to be selling my Brother 4500d and I'm worried that I won't get much for it - even though I can count on two hands the number of times I used it... but it is what it is, right?
