Vacumb & Contact Frames

Hello,... I'm ready to declare myself capable of enlarged negs, and thus
want to start printing bigger than my current 11x14 inch in camera negs. I
will be printing platinum, cyanotype, and perhaps gums up to 20x24
negatives. So, I either need a very big (24x28 or larger) contact frame,
or a large vacumb frame. Seems to me that a contact frame that big will
have problems (out of contact areas printing "soft").

I would love to hear from anyone with experience with contact frames this
large, or from anyone with ideas on either a good used or homemade vacumb
system. I know nothing about vacumb systems, don't know what to look for.
I would like to work this part of the system out before I build the light
source. TIA
