Sigma 70-300mm f4-5.6 APO Macro Super DG Lens

[Invasion]

Getting back into DSLR photography after a while without. Was just wondering,if the sigma 70-300 APO was still a good buy ?

I had one a few years back and it was quite good:when I eventually got a good one. it was a case of 3rd time lucky, first two where not the best, in terms of sharpness but the third was very good.

Will be going on a canon 600D
Thanks

I thought things might of moved on a little. Think I will look at the Tamron 70-300vc and the canon 55-250

I got a 50mm prime 1.8 with the 600D which both arrived today. I have one little concern with the 600D. On the grip side, seems to be some flex in the plastic when you push down on shutter; So the gap move's slightly (if that makes sense, Anyone have this ?
