I had a look around the net and there seems to be others but some starting at $150 and they don't look as fitted so the overall cost does not look too bad as half the time these guys seem to make their money off the freight.
I understand about the freight, they know how to charge but I may be tempted for 2 sets. See if you could get any more interest and get him to lower the price for freight per unit $43 for 1 to $27.50 per unit for 4 is getting better.
Any other takers?????
