I particulalry like the Senator's cloak at the above site.

Look for the Drover's or the Dickensian/Inverness cloaks on this page. I have a heavyweight Inverness in grey/black tweed that is fantastic, and the price is right, and probably not much more than a simple oversized lairds plaid would likely run you.

Just some options to consider. Good luck with your search Geoff.
