Ok, a couple months back I sprung for the Sony 70-300mm G. LOVE it! I have a few wider lenses I've been trying (older beercan - not impressed, 35-105mm Minolta that I just picked up and another one on the way I got cheap with a Maxxum 3XI package...jury's still out on those of course), but I'm looking for a solid performer/go-to lens to round things out (can't afford any G glass at the moment).

I'm considering the highly (Dyxum) rated Sigma 28-70mm F2.8 EX DG, the Sigma 17-70mm F2.8-4.5 DC MACRO, the Tamron 17-50mm F2.8 XR Di II, or possibly the Tamron 28-75mm F2.8 XR Di.

Eventually I'd like to round things out with a super wide Sigma 10-20mm/Tamron 11-18mm, or the Sigma 12-24mm (pretty pricey, tho' full-frame) and the oft' discussed Tamron 90mm Macro. (I wonder why Sigma doesn't make a 15-30mm for Sony?)

Can anyone, <ahem> Don, shed some light on my choices?

Much appreciated,
