If your after a nice gat...Kitch used to have an IR3, Chrome CC jobbie, with A4 Board and Bolt, and I think its a Slayer trigger...so its an A4...my mate has it at the mo, and will sell it to you for £350. He also has an Airsystem as well, not sure if he is selling it...I have tried it, and I'm not the biggest Angel fan, but was going to buy it, for fun!!
Anyway, post if your interested.
