Building Maple stand need inexpensive wood supplier


I plan to replace my MDF shelves with Hardwood Maple. Prices on Ebay are high. Can you recommend a hardwood supplier with reasonable prices. I am in San Diego. 24x 18 x 1 1/2 to 2" thick.

kavakat1, 
The maple you're looking for comes from the Northeast down to the Mid Atlantic region. As akg_ca noted, air dried material is preferable and surprisingly different from kiln dried. It takes at least 2 years to air dry freshly sawn 2 inch thick maple so it may be tough to find a local supplier. You might be able to find a local woodworker who bought in bulk that can help you out for a reasonable price. Failing that, the Mapleshade blocks, seem to be very well made.

Based upon the prices I have found, I am considering another material. Basalt pavers or slabs are heavier and higher density than granite.  They are light only on the wallet. I invite your thoughts and suggestions. 
I’m a big fan of Bluestone pavers. They sound wonderful with cones or springs.
