Stef, the new deluxe one is available at Joann's but the original one might wind your bobbins and it is a lot cheaper. If you can I would try out your bobbins on someone else's sidewinder first. Then you can be sure if it works before you decide which one to get.
Right now at our Joann's the deluxe is on sale for 10% off which seems to me a tactic to simply prevent people from using their coupons on it.
