I'm really just a newbie/hobbyist, but about the only thing I have to complain about with the BitScope is that the sampling frequenzy is a bit slow and the buffer size definately could be bigger. Isn't the Intronix buffer size limiting? At 500 MHz I'd expect it to fill upp pretty fast.

The janatek software can also be downloaded and run as an offline demo, and I must say the software doesn't feel very polished. Seems they've put alot of time into the hardware and maybe not so much in the software. I really don't understand why even in this age some software makers make their own scroll bars and levers instead of using the standard API's for this. I just tested it quickly last night so I'll give it some more time before a final verdict.

I read some specs about the Janatek where they quoted that the 4K buffer at 500MHz only was with certain models. Doesn't that sound odd? I'll have to try and find those specs again.
