I too have used wildcat but have no experience with hightech. I have installed probably 15-20 over the years and have had no issues. As mentioned they are a bit of work and it can seem intimidating at first - but it's pretty hard to wreck anything past the point of being able to fix it. The model 7 pattern is my personal favourite of his offered stocks. If you buy it in the "ultralight fill" you should be able to fully finish it (including a decelerator 1") right at the 19.5oz mark +/-.
They are super stiff, super light - without getting cheesy. I have bought blanks from two other companies because they were lighter - neither were even close to to the quality of a wildcat and by the time I fixed a few issues, they were within an ounce of a wildcat that is properly made from the start.
I will repeat what Dwayne said about cost. If you finish it yourself - they are a bargain. Pay someone to finish it, and costs can climb very very fast.
