Do you need co-location though? I dropped an HP Microserver at a friend's place, which backs up snapshots of my main backup server at home daily. Seems to work well so far, at quite limited costs. Since my main backup server also backs up his NAS we both win. Since all backups are encrypted there is also little privacy risk from theft (or snooping on one another).

With 1Gbps symetrical connections slowly becoming more frequent this would be a much cheaper alternative (assuming you only run it for backups, I also run a mail server and some websites). But in London it is not very practical. I know very few people who have really fast broadband.
