Tradeoff: HTC trackers - worse battery life, larger, slightly heavier, slightly more expensive, uses more USB ports; potentially better occlusion tolerance, you can buy them right now and not wait 6 months, and there's no kickstarter risk.
Tundra trackers - better battery life, smaller, lighter, cheaper when you account for the USB adapter handling multiple trackers, single USB port, better mounting options, saying fuck you to HTC; in exchange you'll have to wait, there's the risk of the kickstarter failing (low as it seems with an established company like Tundra), could be delayed, potentially worse occlusion handling from being smaller/lower profile.
Decision is yours.
