Can't beat Shoup.. get it to you quick and can point you in the right direction if you're unsure about what you need.  The free shipping over $200 just about covers anything you need to get from them, and I always try to have a good idea of what I need for spring and even combine maintenance if I've had time to check all that before the NFMS, 10% discount if you order a couple weeks before the show and pick up there.
