Air Bleed Alternatives

I am following this because I just bought a new holley main body with adjustable air bleeds for my 750 DP and a wideband A/F ratio gauge. I checked Summit and Quick fuel has kits with a range of 10 numbers and it says there are 4 of each size. They are $52.00 per kit and I think one kit would cover the idle air bleeds, and you would need another kit covering the range of the secondary air bleeds.
