[Closed] Please help me find a Cross frame

Hi,

I am looking for a cyclo cross frame. However, something a bit particular, well not that particular. Something a bit like this: http://www.nashbar.com/bikes/Product_10053_10052_173397_-1_202650_10000_202337.

The restraints are as follows.
Lightish. ~1600g. Planet x uncle john is too heavy ~1800g
Disc brake mounts. (I am not looking for a discussion of disc brakes on CX bikes...)
Cheap. £200 would be absolute max. Seeing as though i will probably have to get two.
Aluminium. Carbon is too expensive and breakable.

I will also need to get carbon forks with disc mounts. I can get these on ebay but they are fairly expensive ~£115. Need to be light as well ~550g.

Thankyou,

Michael
