A full-length, waterproof trench-coat. (That won't break the bank!)

[GoodyGoodyGumdrops]

I love my Lands End down Commuter Coat, and they do a waterproof trench-coat, but it's too short. I want a coat as long as the Commuter Coat.

A Drizabone would probably be at the very top end of my budget (do they have sales?) but I'm wary of waxed cotton - the smell and rubbing off onto other coats in the wardrobe.

Any suggestions?

My dh has a drizabone it doesn't smell or rub off on other coats, but it is heavy so he only wears it when its peeing down.

Can't guarantee it won't break the bank, but Rohan worth a look for proper waterproof mac if you've already explored Seasalt.
