Keyword is top-notch but poor TLD.
To get round this one way would be to brand the TLD as 'source' just like whois.sc is doing.
BTW as said above, whois.sc might be interested in that kind of name, it just fits well with their business.
For the time being I would appraise at high $$$ but it can be worth much more to the right end user. Hold on to the name and don't let it go for cheap. I believe it can ultimately reap more than $2000.
