Pretty Cool for a track set-up but $1k is a lot of jack (get it) for something that could be handled for less than $150 and nowhere near as cumbersome to travel with and set-up. It doesn't look near stout enough for me to crawl under either. This is on sale this Friday (Black Friday) at Harbor Freight for $69.99 with coupon:
