How about IKO?

IKO is trying to get in the Florida market, are they any good? Price wise they are a tad cheaper but not enough to sway me away from Cert, GAF, or OC. I would be happy to give them a try if a bounch of you give them favorable reviews. I am always a little skeptical of un tested products. I understand IKO is common in the Northern States. So whatchthink??
