Update: Yeah sorry GA2G missed that link the first time, superb list and thread by the way, have got a couple of things off it and learned a lot:
Squire Ex-Caliber 16mm x 0.7m Security Chain (use it in garage with wall anchor)
Xena Special Offer XZZ6 Alarm (goes on my work bike chainring)
Xena XBL2-35 Bullett lock and 1 meter by 14mm chain (Use in garage and in addition to ulocks sometimes)
Good info on chains/anchors/padlocks/ulocks here: http://www.torc-anchors.com/security-chains.php
