Lateral head supports

I need to get some lateral head supports made;;i really like the looks of the ISP'S but i do have to compare prices and go with what is best price;;priced out the ISP at $500.00 ball park;;;is there any other accepted ones out there at a lower price???;;I know going get a lot of smack on this;;can't put a price on your safty but if i buy the best and most expensive of everything for car i'll never get to go down track with it;;i don't have blank check sponsorships to buy the best;;

 

Butler Built is also an approved vendor. I have them and they work fine. I don't remember how much they were though
