you would have to search
through the threads. Awhile back maybe a month or 2 someone asked the same thing and someone else turned up a supplier in Toronto a steel wire company. The min. purchase was I think 80$ for 1foot by 4feet.
the kanthal or nichrome wire I do not think so. They are both easy and very inexpensive to get on E-bay, like 6 to 8$ shipped for about 75 feet.
have fun...
