I actually arranged to have them made last summer with Ben. He quoted me $285 to build up a pair like TusconVX's. He was apparently very busy and didn't get to it until recently.
Due to the extended build time he only charged me $250 with no shipping cost (which was worth the wait for me, having zero toy budget) on 03/29.
It cost me $176.88 to have them Line-X'ed here in Placerville on 04/20.
I had them mounted [welded on] by Ballistic Trux in Rocklin for $100 on 05/01.
Visit Stric9 Engineering online or email Ben Higuera at benhiguera@hotmail.com. Hopefully he kept his notes so he can fab up another pair for you guys much quicker.
