I got a 3-4 ft length of that vinyl coated particle board that is generally used for shelves and cut a bunch of 2in holes in it with a cheap harbor freight hole saw. Put some 6 in pieces of scrap as leg in the corners to raise it off the ground. It cost me about $10 dollars total and can dry about 50-60 bottles even bombers. Now when I sanitize my bottles I just put them upside down through the holes in the rack, they can drain and nothing touches the inside of the bottle so you dont need to worry about sanitizing the rack or any additional contamination. If I get paranoid I put a shallow tray with an inch or two of star-san below the rack for the tips of the bottles to sit in while they drain, but IMO thats over kill. Ill post a picture if you're interested.
