Anyone have any experience with the old school NuArc flip tops? I just picked one up its 66"X50" with the separate metal halide light unit on rollers I assume its a 1000w bulb but I can't tell, its 220volts for one damn bulb!. Everything works perfectly and the the glass is in great shape but I am going from an overhead UV system to this and trying to take the edge off the learning curve. Also if anyone has a fair value assessment on one that would be great cause I was in the dark about how much to offer and that seemed to be the sellers take on the thing as well...lucky for me. The innerweb is saying anywhere from $1300-$4500 for new ones but this one is much larger than anything I could find.
