I am making a freestanding 13' x 13' covered patio. the posts in the 4 corners will be 6" x 6" x 8 to 9 feet tall. I am looking for connection ideas on the beams that connect on top of the 6" x 6" posts. I will be using either 6" x 10" or 4" x 10" beams. I know Simpson strong ties has a [ECCLQ-SDS bracket](http://www.strongtie.com/products/connectors/ecclq-cccq-cctq.asp) that will connect two beams at the top of each post, but I am just looking for other ideas that might be nicer, as strong as, cheaper and different than Simpson Strong tie.
