For a light tent (also partial windbreak) get a couple of the jointed tent poles for backpacker size tents, some small bungee cords, clothes pins, a piece of black cloth for dark backgrounds and a piece of "translucent" construction plastic for diffusion and make your own domed tent over the subject. Stick a pole in the ground and bend it over the subject, second pole at right angles, bungee them together, drape dark cloth, light cloth, diffusion plastic in the proper places, tie together with clothes pins, crawl inside with your camera (it will quickly get very warm in there) and shoot away as long as you want.
You can also easily make a multi-flash bracket with a short piece of aluminum from the hardware, a couple of adorama standard flash holders, two of the cheapest and smallest used flash units you can find, and a few pieces of white nylon for diffusion on the flashes. You'll have to calibrate it yourself as far as "flash number." If it gives you too much depth of field, Photoshop to the rescue, blur the background.
If you are in the buying mode, look at Benbo tripods - they look weird, but are excellent for getting the camera in the right place (like really low) and holding it steady - I have two and wouldn't use anything else.
Just some ideas that work for me,
