I have gone to my local electronics shops and they have tons of wire, but it is hard to find true silicon jacket wire. Thats what makes the wire really flexible.
I have found some 10 up to 14 gauge wire that has multiple strands, but no silicon jacketing.
While looking the local shops told me that silicon jacket really raises the price of the wire as well.
Unfortunately the local electronic parts store sucks A$$ like you wouldn't believe it. I mean: old women staff it. It's really awful.
I found a store on eBay that would sell some for 10$ shipped (3 feet length of each color). Couldn't find anything cheaper with shipping cost to Canada.
www.stormerhobbies.com has Dean's and Trinity 12g wire. You can also order direct from Trinity too. Most hobby shopps into electric will have 12g for wiring speedo's and batteries.
I get my wires at hobbycity.com , they got everything from 10 to 22ga
Yeah, those wires seems to be working well for me too... but the quality does not compare to the quality of the wires coming from robotmarketplace, I have them all... Just my opinion though... if you're on a budget, hobbycity is excellent and the wires are great...
