Of course don’t know how pricing is in your area. But here Wii’s are pretty cheap. 30/40 Euro’s with a 1 or 2 Wii motes. I even picked up one for free (hardware and software worked, but needed some cleaning on the outside).
If you are okay with piracy a Wii is really easy to hack. With lots of homebrew. So if you don’t mind having original disc’s it is pretty cheap.
If you want something more powerful there is of course the Wii u. Wich can run Linux with homebrew. But they are more expensive.

However seems you already have other plans now.
