If you've got access to woodworking equipment and some scrap plywood, 
you can built one easily enough from parts you may already have lying 
about.  Insulate with rigid foam (polystyrene insulation works fine). 
My only out-of-pocket cost was for the PID controller and some 70C 
thermal fuses (you really do want a safety measure).  Heat is provided 
by a 60W incandescent bulb.    I stack 10" reels of tape using old 
cottage cheese containers, which fit the hub holes quite neatly.

My oven looks like a nice piece of furniture--and even has casters so it 
can be easily rolled around.  Not out of place in a living room.
