Expensive also not neccessary is GOOD

Here's are some suggestions on some key players in the market:

2. Logitech: Famous and also expensive witg quality but their gaming series some how not many and and NO new model release recently. Existing models seems kind of "too normal"

3. A4 Tech: Famous but price is very attractive with many special features that other don't have. Design also unique and have many range. But very ricj guy might not like them as they might perceive as "NOT expensive" enough

4. Razer: popular brand, but not many places availabe
