The Gekko is made by HP Velotechnic but it is not just one trike but four models ranging in cost from $1,990 to $4,980 based on the price list at Bicycleman in Alfred NY.

I think you are looking at it from the wrong perspective as to amortizing the expense of a trike over your remaining years. I'm probably older than you. If someone stole my Catrike 700 I would immediately look for another Catrike, preferably an Expedition or 700 because it is so much fun to ride a really good quality trike. My first trike was not cheap. It turned out to be not very dependable with a couple of serious design defects. It was so much of a pleasure to own and ride my second trike, an Australian made Greenspeed GTO. The basic design wasn't that much different but it stopped faster, handled far better, and best of all I knew it wasn't likely to break down unexpectedly. I rode it 29K miles in 9 years with just one on-road breakdown (not counting flats). Whoever survives you can resell the trike and make a few bucks back. All depends on what you can afford. Any trike is going to attract attention far more than a regular bike.
