Advice Please - Large Allum Tail Box

[kentfallen]

I own a mint 1999 XT600E with only 5,000 miles on the clock. I'm prepping it for a solo tour round European Russia next year (I'm 45 years old so times getting on a bit). I'm doing it alone cos I don't have any M/C buddies and the Mrs hates bikes (dangerous etc...). I have been riding for many years but have never done more than Wales, Scotland and day trips to France and Belgium. The furthest I've been on 2 wheels is the Pyranees in 1993. If I don't do it now I never will. I'm planning the BIG one next June 2009. I am very travelled but not on 2 wheels (worked all over the world but mainly Africa).

I wonder if someone can please point me in the right direction for a good large (50 Litre) alluminium tail box?

I want to spend about £150 if I can plus fittings.

The idea I have is to store my personal stuff in the tail box and dispense with panniers completely. I shall carry a large waterproof holdall on the passenger seat behind the top box and perhaps a tent and sleeping bag on top of that.

As my engineering abilities are not great I'd appreciate the details of someone who could fit the stuff too?

Thanking you all very much (in anticipation) for your valued advice here
