I've bought a couple of logos as well and have been very happy with the result every time. After the first iteration I would give feedback and they would change it accordingly. I don't care if they based it on a template as long as they deliver something usable (it's $5!). It's either that or use one of the lousy logo generators out there. Even if all they do is manipulating a template it's still better than what I will ever be able to do myself.
There's a lot of danger and unnecessary pain in it for a founder having a logo that's a liability. Not uncorrectable after the fact, but why do it in the first place?
