Reasonably-priced nut-plate drill jigs?

I checked at the Avery and Cleveland site for nut-plate drill jigs. They both want about $40 for each size. That seems a bit steep to me. I found some at "The Yard Store" for about $18 apiece. That sounds more reasonable. Does anyone have an opinion about the relative quality of these sources?

Also, does anyone know what sizes I need for my RV-7?

Thanks,

Yard Store

Kev ... you can do #8 and #10 with a #8 nutplate jig....

All of the nutplates we use have only two spacings of the mounting rivets.
A #8 nutplate jig will also do #10 spacing, and a 1/4 jig will do the larger sizes

So for a #10 nutplate, just drill the main hole to #19 as if it was a #8 screw, drill the nutplate mounting holes with a #40, and then enlarge the main screw hole to #10.......

The specs. for the nutplate rivet spacing can be found here....

Thanks for the info guys. I guess I'll get the #8 and 1/4" sizes from The Yard Store.
