Has anyone seen this place?http://www.iscbarrels.com/
They're located maybe 10 miles down the road from me. They don't allow local pickup, otherwise I'd probably own one of these already. Not sure how much freight would be, but the barrels are $133 for plain charred, and $260 for heavy toast + char. They're geared toward distillers, but they'd probably make good beer barrels too.
Their sister company sells super fancy oak alternatives, but they only come in 40lb bagshttp://www.oaksolutionsgroup.com/
The chips that caught my eye were the specially toasted ones that were labeled, "High Spice, High Mocha, High Vanilla." they also have a few other oak options I've never heard of before.
