Excellent! Glad to be of service. Just don't tell the wife... The savings will only get converted into shoes...
I think the Speedo works out to be more expensive than the GG one, but everything else is so much cheaper it more than cancels it out. (by my calcs the whole set with senders is over £200 cheaper!)
The chap I spoke to on the phone when I ordered seemed very pleasant, and genuinely seemed interested in what I was building. He also confirmed that the speedo will work with the E30 diff sender, so that's another cost removed.
Their lead time seems a whole lot shorter as well.
