Dave, and all, EVERYTHING involved in DIY machine tools is dangerous. You just need to take proper safety precautions. Filter masks are a good idea, and a box fan blowing across the work area to carry dust or fumes away from you is another good idea. Working outdoors, when the weather permits, likewise. Formaldehyde is a normal hazard in modern houses, among other things. It is in many materials, adhesives, insulation, and many other things. Ventilation is the key to dealing with it, and every other gaseous or vaporous or fine particulate hazard. Filtration is something else that can help. Masks, filters, Electrostatic preciptators, whatever...

If you have a good source of cheap pine, or poplar, or whatever, its great material. MDF is also cheap and readily available, and it is, when sealed, more dimensionally stable than whole wood. With adequate precautions, any of them will work. You shouldn't be cutting any wood without some protection, and some are outright poisonous. Dust in the lungs is bad for you no matter what kind it is. As for gases, even too much oxygen is bad for you under some circumstances. Learn the hazards, and do read the MSDS's as suggested, but don't refuse to use a material or technique because it MIGHT be hazardous. If you do, you'll wind up doihg nothing at all, because EVERYTHING is hazardous.
