Thanks Guys, deffo looking for a Mint VR1, seen one at £1099 with 3 month warranty.
Quite honestly, it's going to be a couple of years (at least) before the VRIIs start to sell for that kind of money, used :|. If price is really driving your decision and you want to buy now, then why not :shrug:!?
Oh No ! I've read the review
now I'm lusting over VR11
Well then, this one won't help either

I can't help much with a comparison between the two, as I have never used the VRI model, but the VRII is an amazing lens

. Over and above all of the superb optical elements (no pun intended) of it's performance, the difference between the VR function on this lens and on the other two (VR) lenses I have had (the FX 70-300mm and the DX 55-200mm) is really noticable. I regularly get ultra-sharp, hand-held captures at speeds of 1/8th or 10th of a sec now (and almost 90% of 1/15th sec shots are perfect, too), which really opens up a lot of possibilities. OK, I don't often
need to do this, but it's great to have the option

.
Finally, if I was to respond to your original question, I would say that the vignetting on the VRI actually looks great in the example shots that I've seen and I too tend to add my own to 80% of stuff that I shoot

.
The more noticeable difference between them is the "foreshortening" effect that the VRII has, as a trade off against it's closer minimum focusing distance :|. Opinion is divided here, as both have their pros and cons. It really depends on whether you want the possibility to get a frame full of face, when taking portraits at 200mm in fairly close proximity to your subjects, or whether you'd rather have the option to be able to actually
get focus when standing 4 to 4 &
1/2 feet away from your subject, where the VRI would still be OOF :shrug: (useful in a press scrum, I would imagine

).
Tough decision, but I can't see many people
regretting buying either of them.
