I have 6 2.0 hosts left that I am building all to be the same. I finished one (without the knob), and the heatsink weighs in at a hefty 14 oz. I expect the prices to be about $80-90 with a focus knob. If you are interested in getting one, let me know.
Ya, all the stripping and polishing is ~$50. Quality wise they'll be on par with yours, but they don't have as many add-ons. Of course if people want more options, they are welcome to add them.
