Went to the Seahorse in Portland a couple weeks ago and was amazed at the selection they had. Everything seem to be in good health and well taken care of. They have quite the extensive workshop upstairs and do custom tanks, lighting, sumps, plenums, etc. He has atleast 500 lbs of live rock curing and I think he said it's $6 a lb. His RODI was very reasonable and he also does premix, I think RODI was 4 gallons for $1 and premix was a little more.
The entrance to the store is pretty inconspicuous, it is on the lower floor on the back of the building with a large parking lot back there also. Either way, if you are planning on being in the area or making a road trip it is worth checking out.
