Yes definitely a good idea. Plentiful, cheap and you can nick it from the IT department at work
One of my mates has absolute miles of this as well so I think I'll go and aprehend some off him. Thanks for the tip!
Another option to think about, I bought 50 metres of 20 core ribbon cable off eBay and it's perfect for pots, so I just cut a short length of either 2 or 3 cores for each one depending on the pot wiring and it keeps them together nicely which helps make the offboard wiring that bit easier. The cores are pretty thick in the one I got as well and it'll last for years
