I've read in places that the 110v lacks the grunt of 240v but having never experienced both I've no idea.
I know for site work and exposed to public 110v is the rule of thumb but for my main use it would be 240v and even if I go work in someone’s house I'd still be ok.
It just seems there are a lot of 110v deals kicking around ebay etc. that are quite tempting. (and I don’t mean from the states so don’t get me wrong

I understand the electric theory behind it P=IV and most 110v equivalents have a smaller P wattage quoted but what is the 'real' difference?
If you have used both with similar tools, which do you prefer and why?
