How many retro consoles do you own?

Me and the wife have only really started collecting, we've got other commitments at the moment.. But so far we have a PS1, PS2, N64 (boxed) and an X-box 360 (boxed). We're looking into our next console purchase and we haven't really settled on one yet.. She knows that I've got my eye on a Dreamcast though. :D 

So, what do you own? Let us know in the comments below..
