Hi Scott, Thanks for fixing the link! I provide tech support questions regularly on forums. There's actually a 48+ page discussion on AVS Forum if you want to read more: http://avsforum.com/avs-vb/showthread.php?t=695589 We have 3 products... the 'OnAir Sasem', 'OnAir Creator' and the 'OnAir GT' (oldest to newest.) A comparison chart can be found on our website, but I'll describe a bit more in this post: http://autumnwave.com/products/consumer/comparison_chart_-_onair_hdtv_products.html OnAir Sasem - In 2003, we introduced this as the world's first USB 2.0 HDTV tuner! It features a Philips tuner and is powered by an AC adapter. OnAir Creator - In 2005 we introduced the Creator. It visually looks similar to the 'Sasem', but the 'Philips' tuner is replaced with an 'LG 5th gen' tuner. (If you look around, the LG 5th gen is the best tuner around! You'll find it in $2000 HDTVs.) In addition to the major tuner upgrade, we also decided to include a license for the nVidia PureVideo Decoder... one of the best decoders in the industry. It provides a great looking picture on your PC / laptop, and allows for 5.1 surround audio. The Creator is powered by wall (AC) adapter, and includes a 'hardware encoder', which takes the load off your CPU when viewing Analog TV. OnAir GT - Introduced in 2006, the GT is our 'portable' tuner. It uses a 'software encoder', so the power requirements are lower. It is USB-powered, and comes with a 'whip' antenna. It contains the 5th gen LG tuner (same as the Creator), and also has the license for the nVidia PureVideo Decoder.Essentially, the GT should fit most needs. (It is our most popular and least expensive HDTV tuner for the computer.) You may want to consider the 'OnAir Creator' if you intend on doing a lot of Analog TV stuff, because it has the built-in hardware encoder. The 'OnAir Sasem' is more of a 'legacy' product. (Most customers opt for the GT or Creator). I sound like a salesperson... but you can feel free to read the 'AVS Forum' thread for some unbiased customer experiences: http://avsforum.com/avs-vb/showthread.php?t=695589 Thanks. I'm open to any other questions from anyone :) (If you're shy, feel free to Private Message me, too.) - Ryan Pertusio AutumnWave Technical Support OnAir Solution North America
