MDF

I made a decision on the print-bed: I'm going with MDF for now. I drove over to the local hardware-store (getting rear-ended on the way, but that's another story) and described the dimensions of the plates I needed. They just laughed at my puny plates and cut them out for me and gave them to me at no cost! Sometimes small things really are better...

I'll get back to the building later tonight, stay tuned :)
