Gunnel Mounted Outriggers?

Does anyone know the best place to get outriggers from? *I'm looking for 15' alum. 1 1/8" telescoping. *The cheapest I've found were on ebay for $274 for the Taco telescoping alum. poles. *
Is there a big difference in quality from taco to perko or tigress, lee jr's? *I can get some perko alum screw together for about 150. *Does that sound like a decent deal?
Appreciate your help in advance.
