Lol really??? You can't compare the two price wise. The built JQ doesn't even cost as much as an unassembled tki4!! You can't squak about the price. Is it a good car? Yes. Does it assemble easily? Yes. Does it handle well? Yes. All based on my opinion of course. Why not try it?
It's a great car. A lot of time and effort has been put into the car by JQ as well as many racers around the world. The BE is a reflection of the time and effort to get to this point and it's really good. Some say it's kyoshoesque without the crazy price tag handling wise. On top of that the support for the car is second to none.
If you're gonna squak at the price get the Kyosho so you can feel better.
Also, just because Kanai built it does not ensure immediate racing success.
