Check out the Brother MFC-J6910 series of Professional Series Inkjet All-in-One with up to 11″ x 17″ scanning and printing. They are priced within your budget.
We have been using a previous model: MFC-6490CW for several years. Although it appears of flimsy construction, the machine has remarkably reliable! The only weakness is a relatively narrow depth of focus. If the material lifts of the platen, say, due to crease, that area is fuzzy. As long as you make sure the material lies flat again the platen, the scans a sharp.
Printing has exceeded our expectations.
