I bought my Quad 5100i used about three years ago and the brick is starting to look a little ratty, a few in the back with the hole in 'em have broke in half. Before the season really started I was going to look at replacing them but my local dealer went out of business and I had a hard time finding a set of bricks on the net and when I finally did they retail for $150.....and they look like they are a different pattern and layout than the ones in there (maybe for a newer model). So am I being too anal? Will any brick just cut to size work? any advice is appreciated......
