Okay...I still haven't pulled the trigger yet...who knows if I ever will. Each time I get excited about the thing, I always think about the negatives that come along with it which usually is enough to deter me.
This time it is the dust from cutting MDF. My garage is not huge in any way (standard small two-car attached garage). My drive is also inclined so it would be impossible for me to set up sawhorses or anything there without it tipping.

This leads into the dust. I'm alergic to dust. No obviously with proper ventilation and by wearing safety materials, I'd be fine physically, but I don't really want that stuff all over my garage or somehow seep into the house!
My next thought would be to cut in out the yard a bit. If I had the cordless tools, that would probably be doable. I only wonder how far away from the house I would need to be (there's only a couple of feet on each side between my neighbors and I) to where things would remain clean and safe for everyone.
Of course, there is also still the inner fear of all the cutting, routing, etc anyway. I've never used a circular saw in my life. I did use a hand saw and table saw, but that was way back in industrial arts class during the 8th grade. That was for a VCR tape box and even it didn't turn out perfect (stain imperfections, a nail slightly poking up from the bottom, etc. That said I still have that box today. I don't think I ever used it to hold VCR tapes though. In the end, it became a nice little storage device for Atari 2600 carts.

I have hard enough time putting Sauder stuff together so I have a hard time imagining putting together a cabinet would be a simple task for me.
