ordering rock

[Atlantic]

i am planing on placing an order for 35lbs of live fiji rock from Jl aquatiics. first off ive never ordered from them so do they have a good reputation? do they carry good rock? and second, ive never ordered rock online before, so how do i ensure i get some good rock, not just a couple of huge dense peices of base rock. im setting up a new tank so this will be all the new rock for my tank.
thanks...
