Yeah I thought it should be the first thing I should upgrade based on all the benefits I'd get from them, it still sounds like it would be worth it based on what you've said.

I guess I'll be saving for a bit longer then. 
  
Thanks a lot for your advice guys! 
  
  
 
  
  
I'll have a look on eBay now and see if I can get a decent set, cheers.
