I love House of the Dead. I'm totally getting the Wii versions.
But if you like using both guns, I'd suggest Johnny Nero: Action Hero. There's a mode made especially for use with both guns.
the dual wield mode was also implemented in Target: Terror which is coming out for the wii soon (strangely enough, this is going to be released by Konami who made the Lethal Enforcers series).
