If there is a Bernina dealer near you watch for their sales. Sometimes feet are 20-25% off.

If you are going to do any quilting (other than free motion) it is well worth the money. However they are very expensive and I would definitely wait until they have a sale. Even if there is not one near you, you can call one, get on a mailing list and then order when the store is having a sale.
