Here is a link to the Techedge website, probably the best value on widebands these days, you can save a lot by doing it yourself.

Either way, $1k is just rediculous if you ask me and I find it hard to believe that the majority of people on the homemadeturbo forum would shell out $1k for this. That's the whole reason we're on this board - we're hopefully the more technically competent bunch.

With that said, what's wrong with the DIY Wideband projects? There's a wealth of good info out there. At a minimum, you can get a wideband o2 sensor for <$200, a volt meter and follow this chart http://www.diy-wb.com/v_out.htm

I've never used any of this info, but it looks to be pretty popular, so check out http://www.diy-wb.com/ if ya want to.

Personally, I think I'm going to buy a data acquisition board for my laptop, feed the various sensors into that and build the gauges using software - like my good friend Ashley (from whom I got the idea from) - check out some of his stuff: http://ashleypowers.com/Data%20Acquisition/daq.htm

It's all about being creative!
