Voted $100+. I don't spend the time, money, and energy making a performace block just to be unaware how good it really is. I already have over $300 just in my REV. designs (and that's with free use of equipment!). I already have over $300 in my testing equipment and will drop another $600+ in it before I have my first completed test bed. Drop in the bucket in the long run. I plan on making several other blocks in the future and will probably have $1,000's invested in them. $1,000 for testing will be well worth it.
Of course this is from someone who bought a CNC mill pretty much just to make blocks with the excuse I would use it for "other" things. Which is actually true. Working on mold for fishing lures to.
