Last summer I purchased this:
http://www.bhphotovideo.com/c/product/640683-REG/Pentax_85101_DSLR_Leather_Hand_Strap.html . I really like it. "Pentax" is embossed on the handstrap, but in the same black color as the leather itself. I rememember reading a review of a Canon user who commented that because of the subtleness of the Pentax label, it didn't bother him to use it on his Canon. It's a little tricky to figure out how the thing works to begin with (instructions that come with it are nearly worthless), but once you get it, it's great for its purpose.
I use it in combination with the OEM camera strap, but often times don't have the strap around my neck now, because of the no chance of dropping the cam using the hand strap (of course, there's always the possibility of me slipping and falling, in which case I'll have to practice a "body roll" fall to sacrifice my body instead of the camera

.)
Final note - even though the part that mounts to the camera base is made of metal, and has a threaded receptor in the bottom, it's not very usable mounting to a tripod - too much flexing, partly due to a piece of rubber between it and the camera base.
