if it were techguy.com it could worth mid-high xx, however, with the "y" in the middle, I guess it is not marketable. sorry
this name should be branded to be valueable, however, a company wont brand it, because it's not obvious to spell correctly (everyone will type techguy instead, since that is the one with obvious spelling)
if you develop it that's another issue, but I dont see value in the domain itself.
