Onyx and white DSlite (EU) and a silver DS phat (US, got it from liksang -- good ol' days). The DS phat has an autograph of 'Yuji Naka' on the top shell though, so it's not played any more.
I have a Red DS Phat but it's not the same as the Hot Rod Red one, just red and black.
I also have 2 Pink DSLs (one is Love & Berry), 2 White (FF3 and Nu-Gundam), 1 Enamel Navy and 1 Onyx (US)...
