I picked mine up at Sewell Lexus via the CL discount when they used to be a sponsor here. I 'think' I paid $450 for mine but that was a while back...

You can try another one of our CL sponsors and use their CL discount code to see what you'll find:

Ok thank you.

+1 for making the car more fun by doing suspension and steering mods.

I got my ISF ECU from the local dealer, in Canada, for $300. For some reason, this one item was cheaper local than if I got it from the US, which doesn't happen often.

You will need a dealer to calibrate it, or DIY with Techstream. I won't say how, but you can google how to get it for like $20.
