The old Bunk and Junk only has to hold still for 1/15th of a second. It can wobble the rest of the time. Just saying.......

(with studio flash, maybe only 1/100,000th of a second)

Actually, what's fun and not really very expensive for the type of work you described is the old Century Studio cameras on the 3 wheeled semi-centennial stand. Many have an 8X10 back but most were downsized to 5X7 reducing backs after film prices went high post WWII. Nice to have both. 8X10 paper negs are a lot of fun.
