Here is a link to Craigslist in Atlanta for a pair of SDA's. Although I know little about the SDAs, there seems to be a strong following out there....

Or best offer. Model: SDA Compact Reference System. Fine speakers with wood cases and an "umbilical cord" that connects the two speakers so that crossover is canceled resulting in VERY high end stereo. For the true audiophile.
(Although I am not interested in Speakers themselves, I work for FedEx in Atlanta and can work out shipping for you for a small fee. Actual shipping costs would depend on where you live. You would need to contact the seller to decide if you want them and then let me know)
