I'd suggest a different direction. If you are sincere about the $400 limit, I would go for a used set of irons. I would look at any local golf stores to see what they have for trade ins and I would look on the net for used equipment if you are comfortable with dealing that way.

As for specific clubs, I'd suggest the latest model of Pings that you can find in that price range. You should be able to get G2's I think. Also look at the Calliways. You should be able to get alot of club for your money. I'd also suggest taking any money you have left over and using it to have a golf shop set the loft and lie on the clubs. More and more often, this has to be done with brand new clubs straight from the manufacturer.

Best of luck. Hope this give you something else to think about.
