Hey everyone,

I'm finally going to buy myself a PC based oscilloscope and wanted peoples' opinions before I spend a few hundred dollars on something that may not perform. I will be using it for PIC's running at 4-20MHz, serial coms from pic to pc, logic, pwm etc. as well as learning a bit more about power supplies and noise in circuits.

I think i've narrowed it down to two:
DSO-2090 USB - AU$349.95
http://www.darkwire.com.au/html/dso-2090_usb.html
Max. sample rate Realtime sampling: 100MS/s
Bandwidth 40MHz(-3dB), Single shot bandwidth:40MHz

- or -

DSO-2150 USB - AU$419.95
http://www.darkwire.com.au/html/dso-2150_usb.html
Max. sample rate Realtime sampling: 150MS/s
Bandwidth 60MHz(-3dB), Single shot bandwidth: 60MHz


2 questions -
- Will these suit what I want, or has someone found something better out there?
- If so, is it worth the $70 difference for an extra 20MHz?

Thank you all.
Tom.
