That's what I got. I'm not crazy happy with it, but it does the job (for my sons games). I can tell the Pentax 55-300 is a better lens, but I was also on a very limited budget so the Tammy was what I could afford. Go with the LD DI, as the DI coating does make a difference apparently - at least mine doesn't have a lot of purple fringing, which was a problem with older versions. By the way, KEH has the Sigma APO DG for a pretty decent price, I think that's a better lens than the Tamron as well.
