I have a MC10000 and I am more than happy. The two friends I sew with have later versions ( Janome 11000 & Quatro)
but I manage to do more embroidery because mine is pretty straight forward. I think you will be more than happy with the Janome and I hope you have as much fun as I do.
If you haven't had an embroidery machine before Look on the internet for free embroideries, there are 1000's out there.
Embroidery Library is a good site at very reasonable prices. I have also bought a lot from Adorable Applique. They have specials I think on Wednesday & Thursday. The sale designs sell for 7 cents or 75 cents. All very cute because I make mainly children's quilts.
What I do when I buy from a new site is do a couple of stitchouts on muslin. This is advisable for freebies too.
You are in for some real fun.
