I only replace mine when the old one breaks - always the same MX518 family - love em, tried others but this was made for my hand!
Well yes, I have used that mouse and it is ambidextrous. I am currently using an MX518 and in everything other than the fact it doesn't fit my hand, it is way better.
TAKE BACK THOSE LIES.
In your face, Inferior mouse user

Just to make this post a non spamming legal piece of text.
In answer to the O.P.
Never as I own an MX518 & once you have one you have it for Life+

Anyone got a Razer mouse? Now that they are 100% lazer they might be decent as opposed to the one I had which was a lazer tracking a ball which broke twice and I couldn't be bothered ringin up to exchange the 2nd one after the hastle I got with exchanging the first. Mentioning no names about the supplier!
pretty much all microsoft mice are designed for either hand!
