[TriEmbed] MSO may grow on you Re: Budget minded oscilloscope

[Charles J. Lord, PE]

While everyone is hopping on the discussion, I also would plug my Salae
8-channel. The software continues to improve for it and it does all of the
serial/i2c/CAN/etc protocols that I have needed (so far). I keep saying I
will get a digital scope when my Tek 475 dies, but I think it is going to
live forever LOL.
