If you sell your Wii to buy another 360, 2 months from now after your first one is repaired you'll be left with no Wii, 2 360s, and maybe the burden of finding another Wii if you so desire.
Short term, your solution works.
Long term, you'll likely be a worse position than when you started.
As for Wii prices, I'd say you could get decent money on it if it's condition is like new.
