When I got my first LF camera, an Anniversary Speed Graphic, I had no darkroom. I started contact printing with a contact frame, three trays, and fliping my laundryroom lightswitch on and off.
After my third round of printing this way, I went to my local used camera shop, and bought the cheapest 35mm enlarger they had to use as my light source. I also got an enlarger timer, and a set of MC filters.
I still use it for my contact printing. I just hold the filters under the enlarger lens.
