I think i would go with Travis up there,His price is about the same and you get it a little bit lower with his set up.The company on ebay i have never heard of but they have a few bad yelp reviews
https://www.yelp.com/biz/grunion-fabrication-phoenix Travis aka Pro Performance i never have bought from but i trust him,To be a vendor on here which not just anyone we let be one.He knows his stuff and i have yet to see anything bad about him yet and doubt i will.
