So far I'm only gonna be in the artist's alley at one Convention and that's a local con: River City Comic Con

It's been a tough year monetarily for me and I'm trying to save as much money as I can as I'm trying to raise 7k for a technology overhaul (New, Custom Built Mac computer, Scanners/Printers, storage devices and hard drives for said things). I'm in desperate need of new technology and if anybody's familiar with any good scanners/printers would you be as kind as to recommend them to me? I'm looking for one that'll scan and print various sizes (Possibly up to poster sizes and junk), but I'm just looking for a good, solid scanner/printer.

I'm also gonna be running preorders on new products hopefully soon (Pencil/makeup cases, prints, t-shirts, buttons, stuff like that) so watch this space if you're interested c:
