Re: $200 is a good price on a stadolin, right?
Good price, depending on condition. The Parlor in Knoxville currently lists six Strad-O-Lins, all priced $4-450.
And since you're dealing with an antiques dealer rather than a music store, you might find some room for negotiation. Strad-O-Lins are the "ugly ducklings" of old low-to-mid-range mandolins, surprisingly good sounding for their no-frills (generally) construction. I bought my Strad-O-Lin badly cracked for $25, spent $1-200 getting it fixed and set up, and have gotten decades of use out of it, from live performance to recording to just jamming.
For the asking price, or especially if you can bargain with the dealer, I think it's a decent purchase.
