Good advice from one and all--if you can keep all these things in the back of your mind as you trek through the crowds and heat, you'll find the one you are hoping for. I've left out a step or two in the past and came home with the machine anyhow, only to find out it wasn't such a bargain after all; but at the price of today's new machines for what you are getting, some diligence on your part will pay off big.
