New Sigma 18-250 OS vs 2nd hand Nikon 18-200 VR I

[Epoc]

Hi All,

I have a few OS holidays coming up and am looking to buy a bit of an all rounder rather than carry around a heap of glass. Now I realise that these sorts of lenses are a compromise and I am prepared to wear this.

At this stage due to my budget of around $450, I've narrowed my choice down to the a new Sigma 18-250mm OS HSM or a 2nd hand Nikon 18-200mm VR I. They go for around the same price. At this stage I'm leaning toward the new Sigma, 2yr warranty, slightly longer and it's new.

I'd like to hear people's opinion of what they would do being in my shoes, especially from people with experience with these lenses. Oh and feel free to suggest other lenses. My decision in not set in stone.

Cheers,
Epoc
