I've heard that between Britpart and Bearmach, that Bearmach is a "better" brand.
If you go directly to the Bearmach website they have a few bumpers:

I chose this tube winch bumper which was on sale to see the total price with shipping:
A bumper absorbs impact and protects your vehicle and its bodywork from damage. Tubular winch bumpers are also able to support the weight of a winch as well as adding to the overall aesthetics of your vehicle. - BEARMACH Branded for LAND ROVER Discovery 1 (1989 - 1998) 3947

With shipping and sales tax to Dallas, TX, the total came to $520.82, not too expensive. Not sure how long the shipping will actually take with customs, etc.
