Originally posted by hwblanks I've got my own good lens deal in the works--a Sigma 100-300/4.5-6.7 UC for $85 that I found locally on Craigslist. All I need to do to seal the deal is to go get some cash and pick up the lens tomorrow afternoon.
It's cheaper than a new Tamron or Sigma 70-300 and a lot cheaper than the 55-300.

Hi Heather, I hope you're not offended by my unsolicited advice but...
Personally I would not pay $85 for that lens, but would go for the Tamron LD Di f/4-5.6 instead (or spring $200 for the Sigma APO, but I assume you're on a fairly tight budget like me
)
I have not seen that specific lens... but from what I can tell the non-APO Sigma long zooms are not so great. The Tamron lens (I paid $130) or the Sigma 70-300 APO DG will give you significant advantages:
- more room at the short end
- a half-stop faster (significant when you need it!!)
- optical formula optimized for APS-C sensors (where higher /lens/ resolution is required because you're trying to cram an equally detailed image onto a smaller sensor)
- nice build quality, and a very generous 6 year warranty (for the Tamron at least)
So I think you'll get quite a bit more bang for your buck if you go for one of the newer consumer zooms, which are just an awfully good deal in my opinion. I don't want to get into a holy war over which of them is better, but I have been very pleased with the sharpness of the Tamron, and can live with the occasional chromatic aberration.
Anyway, that's just my 2¢!
