I like Suncoast. Just don't loose the Bill of Lading they send you for the core...
I personally rather deal with Suncoast than Goerends', but we're fortunate to have both companies. I'm just kind of weary dealing with a company that as I can tell is built on one man's shoulders.
That said, if I was doing it again I would get one from a smaller company like Hughes or whatever's local. I don't think that either company is worth the premium.
