Affordable is relative.

A bigger problem with the trackers is probably keeping the battery charged until the one time you actually need it to work. That, and depending on how they work, paying the monthly access fee (either to the company that made it or the cellular company that provided the sim card in it) month after month after month -- at some point, you'll have paid more for that than you did for the bike if you're good about how and where you lock the bike, and the bike is not overly expensive.

Probably the easiest thing you can do is to keep track of the serial number of your bike, and use it when you file a police report on your bike if it is stolen. You'd be amazed at how many people have their bike stolen and don't know the serial number ...
