Welcome to WebmasterWorld Guest from 188.8.131.52
I can imagine that all the good names get gobbled up by proffessional domain name retrievers.
If your paying 9.95 as if you were registering a URL then go for it. Hey you may snag one like the pr0n company did which had 3500 backward links to the military website. ;)
"product" domains are easy to re-establish and you are WAY ahead of the game ..plus you saved yourself $299 submission fee to yahoo..
I think I would probably do better starting from scratch and getting it all the way I wanted it from square one. Besides, if $300 a year is too much for an ecom site then I would question what kind of business plan I had from the git go.
