Well I'm ruling out the PR S1. I didn't realize it cost as much as it does. It costs as much as a Losi. I'd buy the Losi first.
So now it's between the Cactus and the TC02. The TC02 has a lot of upgrades and costs $210. The Cactus doesn't even have any available upgrades, but it's only $155 and it can be run mid or rear motor which I like. Plus it looks pretty cool
