I have a new, used X6100 (95 or higher), which I've used a few times. I also have a brand-new, official amplifier that is still under warranty, along with the speaker for 2300. The speaker itself is 2700.
I've already lost a significant amount of money in just a few months, and that's definitely the price I pay for supporting domestic products!
For example, I bought a 450D in early last year and sold it last month, making a profit of 200 yuan (approximately $30).
