Cosplayers! I need opinions on a new Sewing Machine!

I’ve already decided on a Brother, because I hear lots of people like them, including many cosplayers I really respect.  I’ve got it down to 3…

Basic: $80

Computerized: $160

Project Runway Computerized: $150

Don’t ask me why the Project Runway machine, with 80 stitches, by the SAME manufacturer, is less than the 60 sticth machine.  I don’t care about stitches… I realisticaly won’t use 3/4 of these.  What I’m looking for is stretch, durability, and ease in changing the pressure foot.   If you know of one better suited to what I’m looking for, please let me know.

PROS, CONS, GO!
