Camber Kit - Brand & Quality

[Spyper]

I've just been searching around ebay and stumbled across this:

http://cgi.ebay.com.au/CASTOR-CAMBER...QQcmdZViewItem

For those that dont follow the link, it's a 4 brush camber kit. The brand is super-pro. Anyone know if it'd be any good? The price at the moment is $160 and that's a MAJOR advantage over the $400 kits. But don't want to be geting it iif it's useless. Help appreciated thanks.
