Its not a bad price. How accurate would you say it is? Would you buy it?http://cgi.ebay.com/ebaymotors/ws/eB...category=33740

 

It's accurate in testing differences. That is, it will tell you the time gains/losses between different modifications. However it is not always accurate in testing for the actual times themselves. Is it worth it? I think so. It will help you master launches and prove to yourself modifications can make a difference!

 

Thanks for your fast reply, I have to fix my Paypal account. And I will buy one after its fixed.
