I am quite new to circuit bending and I was just wondering which sort of resistors I should be going for. I know that they have different values (10, 10k, 100k etc) I was just wondering if there are some levels not worth bothering with (by anyones standard) and if I should be looking at more than the the 10, 10k, 100k, 480k tag when choosing. Thanks.
Also... Where do most people do their component shopping? I am in the UK so would be looking for somewhere there to deliver. ;)

The search function is your friend http://www.circuitbenders.co.uk/forum/index.php/topic,275.0.html (http://www.circuitbenders.co.uk/forum/index.php/topic,275.0.html)
100R, 1K, 4.7K, 10K, 47K, 100K, 470K, 1M are the values you'll probably use most often, but inevitably until you've built up a collection you'll never have the exact resistor you need, and you'll end up bodging in between values together using other values in series.

So all these fellas are what I am looking for then:

:o
I think I was a little confused before as I wasn't sure if I was meant to be looking at anything else other than the values we have both mentioned.

you don't need 1/2 watt ones. They are far more expensive and unnecessary for any circuit bending job. I'd probably go for these 1/4 watt ones which cost around 70p for 100.

That's great thanks for that. Is it the same sort of deal with potentiometers as they seem to be pretty steep. This the last newbies question, I promise! What are the ranges I should be looking to get a pot in? the reason I ask is because some seem seriously expensive!

Simlar ranges again really.
470ohm, 1k, 10k, 100k, 470k and 1M will be a good range to kick off with, and you can fill out with the ones in between later on. The ones in between will get you a better response with some bends, you'll know when you find a bend that doesn't do anything for half a turn, and has a great range in the other half :)
I think most of us use these most of the time:

It's also worth buying some preset pots (also called trim pots) as well, again in those values. I've not had a problem with using these ones:

I've been buying about 40 pots at a time from Futurlec in the US recently: http://www.futurlec.com/PotRot.shtml (http://www.futurlec.com/PotRot.shtml)
They are very cheap and you can get about 50-60 standard pots before you come up against the £18 limit when you'll get charged VAT and customs fees to import stuff into the UK. Worldwide shipping is only about $4 for orders up to $29. Thats probably 1/3 of the price for getting the same amount shipped within the UK!
