Just for the record.
I don't sell LUT boxes or anything for that matter
. Nor have I ever charged anything for doing a calibration.
You can even get all the software needed for HTPC and 3DLUT's for free.
However you want to commit to learning how to uses these free tools before you buy a color meter.
Other wise you end up quitting and selling the meter/s at a loss, and hire someone to do it for you.
If you are interested In becoming a DYI, I know gadgtfreek seems to have given up on learning how to calibrate and is selling his meter here on AVS. However beware, that meter is licensed for use with CromaPure software, and that software isn't free. So for a little more you can get a new D3 basic, if you look for the sales.
In my case I use a eecolor box and have LS, CM and Argyll software.
Also tools like DCT, Teds disc, Lumagen 2041, Jeti 1211, Klein K10-A.
