I'm ok with new colours, and the layout but a lot of stuff is broken still.

Not wanting to be overly critical, Gary, as a website revamp is a big task, but if this is database driven it doesn't feel like the data is being used effectively or the underlying data model is right; just looking at the stepper motors pages there's a lot of textual description where some efficient use of data would have imparted the same info more consistently. Personally I'd want to see inductance as a key piece of top level info.

Some other things I noted:

Go to Nema23 steppers page and select compare on 2 items... Then what? No obvious next step.

Also on many of the motors there is no detailed specification, or you have to scroll down a long way, or you get some random broken html.

And a NEMA24 motor hidden in the 23s? Needs a warning note at least.
