Get that 24" printer and start shooting off some 24x36" prints, frame them, and realize that your framing costs just shot up astronomically.
So... you look at canvas, gallery wraps, and realize the biggest you can print on your 24" printer, with 2" lost to the wrap on each side, is 20x30", which really isn't that big (especially for something that's not matted). Hello 44"!
Care to comment Brian? (You're right, that the 44" is kind of shocking how big it is.)
