Oh my goodness, what weird timing!   Yes, it's hard to find the 'neatest' design you like, that 'fits' you, when deciding to get a shirt related to your fandom.  I personally coveted this:  http://www.qwertee.com/product/the-boys-of-baker-street/  but didn't grab it.    Besides redbubble though, qwertee is a great place for well done art covering a variety of fandoms.  Thing is, they work by highlighting the favorite-voted one of the day, for only a limited time before it's gone.  And go look at today-only's design:  http://www.qwertee.com
