I was just told about this thread and thought I should reply. I am actually the one behind austinhdexperts. I've been an avs forum member for over 10 years now, and I've been performing display calibrations nearly as long. I've also built complete theaters (for myself and others), as well as do just about anything a/v related. This isn't my full-time job, it's just a passion of mine. I'm mainly a software developer.
I only charge $150 for calibrating flat panel TVs ($200 for projectors), because frankly I don't think anyone should pay more than that. I am very particular about calibrating displays, despite what I charge. I spend as much time as it takes to get great results, which usually means a good 2 hours total, whether it's a $200 32" TV or a $10,000 projector. I've also fixed many horrible calibrations that have been performed by Best Buy.
Feel free to ask me for references or come to my house and see my own calibrated displays. I have a 50" LG plasma in my living room that has an outstanding picture (I love LG's calibration controls), and I also have a Marquee 8500 8" CRT projector in my theater that looks awesome.
And yes, the site is quite outdated. One of these days I'll give it a refresh.
