    Sorry I haven't got around to relying to your PMs - a few personal/work related items to take care of at the moment.

    I live in the UK - so recommending someone in the US wouldn't be my field of expertise. But I know a load of people on VCFED who could recommend suppliers !

    4116s are not manufactured any more - so you would be buying NOS or 'pulls' from suppliers anyhow I am afraid - so just go with a 'cheap' supplier and see what happens...
