I got it 2-3 years ago, and it was among the cheapest dso-scopes around, like $300. I got the monochrome version since color was a huge price premium. It claims 25MHz bandwidth, 250MS/s. The cheapest version lacks front panel usb, but there are some traces going to the port inside, so i might try something out some day..
