Katia,
I have gotten the bug too since the shop has opened. I did have a FW which I really enjoy taking to classes and friends houses for piecing.
I do not have a plan to my purchasing but realize that I need to come up with one or I will buy everything. I plan to use them after I clean them up. My first plan was to not spend more than $40. But now I see the error in that and that with selectivity I will get some nicer machines.
I hope to get something to do FMQ on eventually.
I am also making an organized list of what I have so I can be a better shopper.
