I am about to order a 4 lane 42ft Best Track and I am trying to figure out which timer I should go with. I would like it to show place and time and have display on both sides. As you all know, there are a few options out there. I see where The Champ timer is made just for the Best Track but its the most expensive at $630. SmartLine Pinewood Derby® Timer II (Double Sided Time + Place (P2T2)) is another option and is on sale right now for $479. Lastly, in other post I have seen where Micro Wizard is a popular choice also and the K3 cost is $415. I would like to take in consideration of things like ease of use (putting it together, making it work with Best Track, anything I would need to change out to make any non "The Champ" timers fit and work), so on. I really do appreciate any feedback that may be given. Thank to all!
