Recently I found a good heat shrink starter kit with 160 pieces of assorted sizes and colors (1/16 thru 3/8 inch). The 3/8 inch size is a little large, but considering there are only 10 pieces the overall use of the kit at a cost of under $20 with shipping is reasonable. It is available on the internet at the following location: skycraftsurplus.com 1525.
