Just got this in an email from Lee Valley. This looks like a decent enough set for those who like to make their own jigs.

http://www.leevalley.com/en/hardware/page.aspx?cat=3,45962,51887,65642&p=65642Each kit contains 60 T-bolts (20 each of 1" and 1-1/2? sizes, and 10 each of 2-1/2" and 3-1/2" sizes); 16 T-nuts (4 prong); 16 threaded inserts; 10 round insert knobs (1"); 6 each of 2? T-insert knobs, 4-arm insert knobs and 4-arm bolt knobs; 4 each of 5-arm insert knobs and 5-arm bolt knobs; and 20 washers. The tough polypropylene case measures 13-1/4" x 8-3/4", and has 2" deep compartments with moveable dividers.
Kits are available with 1/4-20 threaded components for general use, or more robust 5/16-18 threads for heavier-duty applications. Available while quantities last.
