You'll want to look at Epson, HP, and Canon - they each get their share of love and hate, depending on the experiences of the owner. I know Epson has decently priced wide-format printers, but I don't know about wide-format scanning, it doesn't seem to be very common. My personal preferences are for a dedicated Epson scanner (I just don't feel the all-in-ones are the best quality, but they could certainly have improved since the last time I needed to buy one), and either an Epson or HP printer - I've had both and liked both.
I love my Gazelle, you'll have so much fun!!
