This is only meant as a joke...and it was hard for me not to say this....
If I had $2000 dollars I would spend $150 on a Brother Machine (Ive had mine now since 2006) and would spend the $1850 on fabric and thread oh and lunch and a pedicure and a manicure and a Good book. LOL
Anyways, I am sure that you will find you a nice machine. And I am sure that you will get lots of suggestions. So good luck to you.
