Best place to buy a GS-911 tool?

[SamN]

Hi all,

I'm considering buying a GS-911 tool and was wondering the best place to buy one or if we get forum discount anywhere?

I had an EML light come on briefly on my 2012 RR, and although it's gone I'd like to check it out.

I'm also considering a Brembo master cylinder upgrade and believe I'd need the tool to bleed the ABS.

Thanks!
Sam
