I don't think there is a "best" place. When I bought mine locally they had about a dozen in stock...one was very special, a few were pretty good, a few were so so, and a few were dogs. So, you'll either have to kick a lot of tires locally or order on line and take your chances.Best place to buy them?
I have the Blonde Ash Tele and it ringed like a bell right out of the box. Upgraded to Lollars and changed the bridge and it is tough to beat. They must have found some exceptional wood for the Ash Tele's.
