Get advice from both club and forum. And from any online reviews you can find. And from your LDS. Ask them all why they're recommending X, Y or Z. And then weigh it all up and see what makes good sense to you.

To be fair it's always great to see new divers go out and buy the most expensive everything and then do their first quarry dive in winter or vomit inducing boat dive and decide UK diving is not for them. It gives the rest of us the opportunity to pick up cheap second hand, used only once, kit.
seriously, buy nowt except a mask and rent or borrow a suit for the first few dives
