Here's an idea I had while browsing Craigslist for a stationary bike.

People ditch these for nothing or next to nothing and if you Google the model number on the ones with screens, there's a good chance you'll find an eBay/other auction - often with bids - for JUST the screens. And they ain't cheap.

The most expensive bike I saw was $100 and the screens ranged from $100 to $350!

Granted, now you've got a screenless bike you have to deal with...but still, I was quite surprised to see people were buying the screens
