4th edition Genestealers

I've just received a set of 4th edition Genestealers (I lost my 2nd edition originals) I bought from Ebay I have to say they are fantastic. There are some very imaginative designs and the Broodlord is stunning. I've found copies of the 4th edition rules and missions, the new rules are much better than the dumbed down 2nd edition. I'm as excited as I was when I bought the original game back in 1989 (I'm afraid I am that old!) I just need the new tiles, and I might splash out on some more metal terminators on ebay or even the plastics from the 4th. I know GW has it's critics and deservedly so some times but I cannot fault the quality of these Genestealers and the updated rule set.
