It has become easier and easier to get access to this type of equipment through hacker spaces and facilities like the Tech Shop, but if you are looking to put together your own serious wood shop, we wasted a lot of time and money before we finally bought all DeWalt tools. Ours is 20 years old, but I expect little less from the current model.
I've already gotten some comments asking for information on how to actually change the blade in the saw, so enjoy a bonus second tutorial just about how to change the blades.
The band saw tracking I mentioned in this second video works on the principle of a crowned pulley. Woodgears has a good introduction to crowned pulleys, as does Make Magazine in issue 22 pp 158-160.
