I know exactly what you're talking about Shaun.
I probably have over a dozen instances now where i could kick myself for my indecision or lack of commitment but sadly ( or possibly thankfully ) i dont have photos of them to hand. I think if i were to go through my old PC & look through the saved images there would be even more than i recall.
Well as they say hindsight vision is 20/20 !!

Lets not live by regrets but hope for the future - i'm off to ebay to find an amazing buy-it-now item !!!
