GPS timers have dropped in price enough that for the most part, the beacon timers are going away. The sport is expensive, no doubt...but short of breaking one in a crash, you don't really lose money buying a GPS timer. You'll take a small hit if you buy new obviously, but it's not like tires or gas. They are affordable enough that if you're doing this for more than a year, pony up the dough and get a decent one. If you get out of the game you'll get 85% of your money back and for the 15% loss you'll take, it's worth it to have a nice quality GPS...at least it is to me.
