We just picked up Nordic as our 3rd and final line of spas and I couldn't be happier, they are basically my favorite "no frills" tub on the market, although now they do have a few little upgrades like external lighting, small LED lit waterfalls, etc. that are relatively inexpensive upgrades that are a nice added touch. Like Hottubguy said make sure they are including the extra Nordic wrap insulation...pricing is right on the mark in my opinion, I have a Retreat MS on the floor with Nordic wrap, lighting upgrade and "out the door" we are right around $5,500 as well. Great little reliable tubs, you basically can't break the damn things, nice little warranty as well, the newest models have a 3yr component and 5yr on the heater which at that price point is very nice.
