Multiple tld impact on domain valuation.

[mhdoc]

I frequently look for domains in the form keywordkeyword(s).tld

If both without the hyphen are taken I check the hyphenated form.
So I would check
watchparts
watchpart
watch-parts
watch-part

I am curious about how significant the fact lots of the potential names, even the less desirable ones, have been taken is to your estimation of value.
