Julians’ wire (and the guy who makes it now) is fine. What I like is his “starter set” has some of all sizes. Then, once the buyer gets it and starts using it he’ll determine what sizes he uses the most, and then he can make future purchases to suit his usage. But, everyone needs to have some of all sizes.
I do prefer Jim Gremel’s wire to Julian’s. Gremel’s wire is annealed in a kiln, to precise temperatures and timing. Julian annuals his in an open fire, and he goes by color. Gremel makes larger diameter coils than does Julian.
Gremel has been hard to reach recently, so it’s probably easier to order from Julian.
Some vendors sell by weight, some by the foot. That can make comparing prices a bit tricky.
There are other vendors. Superfly, Mirai, Peter Tea. I know Peter used to use Gremel’s wire, so he knows how quality wire works, and he tells me that the wire he makes is of comparable quality. When I run out of my supply of Gremel wire, I’ll probably start ordering from Peter Tea. (If I cant get any more from Gremel).
