I've been looking at doors too, as its one of the last things I have do do to finish my studio. I've found a product at Home Depot that I am probably going to go with. The doors are called Safe and Sound. They are interior doors and are available as a knock down ( means it includes frames, jambs, door, etc.) A 32 " wide door kit will run you $155 CDN. They are a solid door. I am going to install a threshold, sweep, and weatherstripping. Hope this helps.
