I don't know if this is a possibility or option for you, but you might want to look into finding a used or consignment sporting-goods store. We have a store here called "Play it Again Sports" that deals in used equipment. They let you try everything before you buy, and while there is never a guarantee that they will have exactly what you are looking for in stock at any one time, the stuff they do have (in my experience) is in great condition and available at great prices. Just think of how many people buy a stationary bike or treadmill, use them once or twice (or for a month or so), give up or get bored, and then never use it again.
I'm just mentioning this because I'm sure that you could get quite a nice piece of equipment at a similar place for your price range. In either case, I hope you have a great anniversary!
