why nobody answered my question the 2D comparision between ST30 and GT25 series....
1. Most people in this thread are G20/G25 owners, not ST30 owners.
2. You've posted your question 5 or 6 times in AVS forums. Each time, you simply ask your question and never show any indication you've done any homework/research on your own. People are more likely to help you if you can show you've tried to figure out some of it on your own.
Also, once you've found a relevant thread, use the "Search this thread" box - it works really well.
