The standard advice is to get yourself down to John Lewis / other large department store / equivalent where they have a range of knives from different manufacturers and try them out for size, shape and weight. Only you can recommend yourself a knife set.
I like Global knives, but many people find them too light. They also lack a bolster and guard, which is a matter of personal preference. Personally, I'd avoid knives with a guard, as it prevents really smooth use of a whetstone. On the subject of whetstones, buy yourself a decent set. The knives and everything you need to keep them in top condition won't come cheap as a package, so factor this in.
If you prefer, buy them online when you've decided, but be EXTREMELY careful you're not buying forgeries. If the deal's too good to be true, it almost certainly is.
