I found this on ebay:

1200/46 Litz.  It is NOT cheaper, but he allows you to buy in 10 foot increments. For instance 30 feet for ~$48. This could bring your cost down a bit, if you are not going to build more than one FSL
Gary do you think that this wire would be equivalent to the 1162/46 wire that you called out above?
