So whats reasonable?

I'm new to this commissioning thing having just started getting my first few commission recently. After reading a few of these horror stories from all of you and as a concerned artist who wants to do more commissions in the future, I ask you all.

What do you consider a reasonable amount of time for an artist to finish and complete a commission?

We all know that artists have lives, jobs, and interests outside our art that art important and some commissions/artists take longer than others (such as an icon verses a 2 character full color image) But generally give me a fiar time frame by you, as a commissioner's, stand point.
