Which model frame are you thinking of putting together? Nrs is closing out a couple frames right now, bighorn I for about $550, bh II for around $700. Be careful of putting any full priced parts into a used setup, just because stuff de-values when it's not "new" anymore. Think the old style 6" towers are still on sale for a tower option.
We can't always agree, but we can still be civil to each other.
