How can you know at all. You don't know the OP and any fit issues he may have. What some of the others have said, get yourself(the OP) fitted properly for your bike. It doesn't matter if you spend £200 or £2k on the bike it won't be of any use to you if you can't ride it.
My thoughts would be at that price, buy a quality frame/wheels and cheaper components. The components will wear out anyway in time so you can upgrade later on.
