i agree with lord of the reef, and as for buying rock that is dead except for bacteria, you seem to be misinformed, lr is lr, and unless somone actually cleans everything off(which is nearly impossible), it will regrow, which after the die of, you won't be much further ahead, by ordering online,
on my lfs rock, i got polyps and feather duster, a crab, good coraline(in 6 months), a nudi, lots of pods, a mushroom, worms, and some macro algaes, as well as some clams, admittedly it was brown when i bought it but now it isn't
and on my MO, i got coraline(most of which had died), a nudibranch, some worms and pods, and the size was the only thing i did not like(most pieces were smaller than fist sized), and it took mcuh longer to cycle with(in my case)
now, every piece you get will be different in life and everything, so ordering online or locally just depends on the piece you pick up
as for the type, i have mostly fiji, it is cheaper in most cases, and has a smaller chance of carrying a mantis than fla(IMO), now i do not live in fear of the mantis, so i do not solely base my decission on this(price is very important to me too) because in all instances there are chances and normally they are very small
i have bought both, and am not completely disappointed wiith either, with the exceptin that many online places do not give you the option of size and shape, this is important to me
and i have heard nothing bad(in fact alll good) about swf's lr
