I bought 120lbs of LR from
http://www.intmarinefish.com/ they were really good to work with. I called them on the phone told them what I was planning to do and what type/color of rock I wanted and that's exactly what I got. They sent me a bunch of very nice flat long pieces that I built a "SPS Walkway" with The rock I got has green/red/maroon/teal/blue/orange colorations from the different stuff(I know it's a technical word) that was on the rock. I would buy from them again. and their prices weren't to bad.
