blah....on ebay you can get 75ft for $3.75 for kanthal........
The first one i posted is for Resistance wire it is $25 for 75 feet. The second link i posted is 20 feet of .999 fine silver NO resistance wire.
32 gauge 36 gauge is a personal preference. 32 gauge is less resistance per foot for instance a 1.5 ohm coild with 32 gauge is about 1.25 inches where as a 1.5 ohm coil for 36 gauge is about .50 inches so requires a bit more precision to wrap the coil.
I have only tried 36 gauge nichrome that shipped with ody and i did not like it. Also there are some differences between kanthal a-1 and d and im not sure what they are or if they effect vaping... maybe fright could chime in with that.
