Would it be sensible to spend £100 on one from cex for the warranty?
Yes. 2 years is a fantastic offer.
I bought one for 80 quid last year. Premium Edition all boxed and mint condition.
As a family we still enjoy 4 player games on Super Mario Wii and the Wii U edition. Massive back catalogue of Wii games which look great in HD, also bought most of the online console games off the store which also has the original Bomberman games - more family 4 player fun.
We still use the Wii Fit board which works. I just seen it as a way to play more Nintendo classics with the added bonus of HD, a HDD and access still to Nintendo exclusives.
