I think I've sold just over 100 but not positive. I've sold some on Ebay in the past. Sold some on here and other forums for reseller prices and I've had a few good private sales too.
I started my domain business on last Aug. Still in thelearninf stage and totally sold about 80 domains since then. But most of my sales are low bucks business.
I did buy some trash names especially at the beginning, but now my portfolio looks much better. The highest sale I have is $1050 only for a CVCV.COM name, and have about 6 sale between $500 - $1,000. Others are very low profit.
In a general, the total investment I spend for domaining is about $12K, and total sales is about $7K only, so I don't make break even yet. (Now I have about 220 domains in portfolio)
Hope could get business in mid $x,xxx range in 2007 and make actual profit by year end
