Surely its not all about cost but how good the surgeon is. I know money is a big part, if like me you haven't got lots of it! I have thought a lot about this and of course I want the best for as little as possible thats why I've decided to go aboard. I've not decided where yet but I have found a site that has reveiws from people that have used the different clinics. The reviews are very interesting and mention things I've not even thought about!
Take a look, I hope it helps
