Thanks for posting this because I'm looking to buy one also.
I had a Deco 600 many years ago paid over $3000. for it when it first came out within in a couple years you couldn't upgrade and it only worked on wins95 so I sold it about 4 years ago. This was before I started quilting I had quit sewing period for many years and didn't think I would stated back boy was I wrong...
I know I won't buy a pricey one cause they change so fast.
I hope you keep getting info so I can learn more also.
Have a blessed evening

i have the brother 4000D and love it also always stuck with brother
