Ray, sparkfun have an interesting read on re flow. Their (and many others) preferred device is an electric skillet. I find this astounding as I have never seen one that can heat anywhere close to evenly.
From my readings, one should use clean, dry sand to provide a layer of heat distribution. One poster stated that white sand sold for fish aquiriums was perfect.

i've seen a 10mm thick lump of aluminium used in the same way. i suppose anything flat and really conductive would do the same. you'd probably need to clamp to stop bend, not a problem with sand.
rapidly cooling down either would be interesting.

In my imagination the stove top heats quite evenly across the glass. If this is not how it is in reality, then I also have a 400 watt halogen in the same shed..........
