I have a Memory Craft 8000 made by Janome that I bought about 18 years ago. It is a work horse and like someone else said, "it sews better than I do!" The only thing I've done service-wise is have it cleaned and whatever they do when you take it in for a check up and I had to replace the light bulb (spendy little puppy) and the bobbin winder died so I purchased another one (equally spendy little puppy) which didn't last too long before it gave up. Not complaining here! I love this machine and I bought a $29 Side Winder to fill bobbins and I'm happy as a clam with that, too. I'd love to have the new Janome 11000 but that might have to wait about a hundred years or so until my MC8000 dies and I don't want it to go anytime soon.
I also have a Brother XR-65t which I use for quilt classes. I LOVE IT! Someone else on this thread said they had one, too that they liked. I don't think that model is available anymore but a friend of mine bought the next generation of the Brother and loves it. Don't know the model number on my friends.
Forgot my manners...welcome to the board! I know I'm very late with my welcome but just found this thread this morning. You'll learn lots here.
