Total hip replacement countdown: 1 month

The bad news: We were bumped to Jan. 3 for the hubs' hip surgery due to the hospital's busy schedule. (Apparently, there's an end-of-the-year last-minute rush for ORs.) The good news: He'll be up and running (well, more like limping along slowly) for the holidays. Beyond stopping certain medications and supplements on a timetable, there's not much prep required....except for the post-op exercise plan. Treadmills are out. Ellipticals, too. So, we're shopping for a stationery bike.  I'm looking at the Schwinn AD6, seen above, and wondering how far the price will go down right before New Year's Day. This will require more research. Anyone have any experience with pricing/buying exercise equipment before making your annual resolutions?
