I've read this thread from begining to end and two things stick out;
1) Several monkeys out there honestly think it is worth spending 130 notes on a chain which will be chopped in 2 or 3 secs by a determined theif! (Yes there are people out there with hydralic cutting gear just like the fire brigade or just cutting disks!
)
2) Paranoia - net.... Now that I like! It adequately describes certain people on this forum!
My advice, hide the bl**dy thing!
You can't find it, you cant nick it!
