Affordable 100MHz PC DIY oscope

[msysta]

DIY scope made of FPGA modules.

Attached to PC via RS232 and capable of 100MHz sample frequency...

Oh, and the price: That's about $90.75 so far.

Interesting, eh?

Has anyone tried this out yet? Seems that on that page there's also other interesting projects...

And if you don't want to do it yourself, here is other PC scope, ready made and very unexpensive too... Not 100MHz anyway...

limitations

I've looked at the Parallax scope, one review warned about a limited overall voltage range (20v overall = +/-10v).
Attached PDF is a review of several computer scopes.
