You need to justify that suggestion. OP has £60 for a mouse, the MX518 is an £18 mouse. It's like recommending a Mondeo to someone with the budget for an Aston Martin. Yes, the MX518 is great, and probably unbeaten on price performance, but it isn't the best mouse for sub £60 in my opinion.
Just because he has £60 to spend doesn't mean he needs to. I was also going to suggest the MX518.
It's a fantastic mouse; Mine has been going strong for 2 years now and I would gladly buy another if I needed to.
