I have a Precor AMT 885 with Open Stride that was purchased used, and it's great. It has a monitor, but not for tv (gyms can hook it up to some sort of video, but all I can get at home is the work out screens).
Edit--This would probably be out of her budget (we paid $3200 used, and they're over $12K new). But for anyone considering gym quality equipment, consider used. The gyms, like car rental companies with cars, only want their machines when they're really new, and they replace their equipment within 2-4 years, usually.
