Sigma or Tamron macro lens

[moonraker]

I am thinking of getting my first macro lens. I have been looking at either the Sigma 105 2.8 DG or the Tamron SP AF 90 2.9 Di Please could any one give me any advise on either? I will be using it on a Nikon D80 for photographing flowers and possibly dragonflies and lizards.

They're both very highly regarded so you're not going to go far wrong with either. I'd either buy whichever one you can get the best deal on or if similar price, go for the Sigma just because that extra 15mm which might help with live bugs.
