It all depends on how much you spent on it. If it is a hand reg then it is not a complete waste of money. TechBoss.com would be better but is already taken.
Could be a good name for tech review site, technician management course etc.
I would price it at low $xxxx and wait for offers.
TechBoss.com would be great compared to your TechieBoss.com,
I see no value here, even if you give it free for me, I won't take!
As per my suggestion, simply put it for sale around 150$ - 350$ and don't renew later!
