After weeks of looking around and researching, I've decided to proceed with my build. I am using 15 series 8020 extrusion and borrowing a lot from Glacial Wanderer's design. I have already bought most of the 8020 needed. Details are as follows:

1. 72" x 37" table dimension. I know this might be a bit too big especially since I am planning on 1/2" acme lead screws, making screw whip a concern...will most likely go with a 60" length and see how it goes. If whip is so bad, I can always cut further. Rack and pinion is out of the question for now.

2. After hearing all the good feedback, I've settled on CNCRouterparts for th bearing blocks, linear bearings, Z-Axis plate, and AB nuts. Ahren, I will be getting in touch to put in my order soon!

3. Kelling Bipolar Nema 23 Stepper Motors and drivers. CandCNC UBOB. Haven't made my final choice yet, but I am looking at holding torque in the high 300's to mid 400's range.

4. EMC or Mach 3 software. Again, haven't made final decision yet.

I will be usign the router primarily for making giant-scale RC Airplane kits, propellers, and MDF molds for composite lay-ups.

I will be posting pics and and a log of my progress as soon as I start building. Any feedback or comments are more than welcome!
