Hi Peter
Many thanks .. that was quick

I got some from a local shop, in a pack of two hinges/ball joints. Sort of polypropylene mouldings, very cheap, and somewhat nasty ...
Not a very good shop, more for plastic kits etc. rather than anything more serious ..
Would like a source on mail order if you have one.
I'm fooling about with Picaxe/PIC's at the moment, so I need to get a couple of servos anyway.
Not that I have any specific use for them. Just want to have a play ....
