Anyone care to compare the two brands. I am looking for a 100 MHz, 4 ch scope.

If you aren't particular about USB, you can get a nice refurb TDS744 for
less than $900 on eBay. An hour's work turns it into a 4 GS/s, 1-GHz
TDS784. (I've done two of them.)
They're reasonably simple to talk to via GPIB, if you have a Prologix
GPIB adapter. Simon and I have been taking a bunch of laser noise data
that way recently.

How much are they. I really want a keysight 'scope... I think the
4 chan low end is >$2k.

I can't speak to the Siglent's, but I own (2) Rigol scopes myself, and we also use several Rigol scopes at the shop.
I own a DS2302A and a DS2072A-S.
Both came with the advanced triggering & bus decoding options add-on for free.
Rigol scopes are easy to use and a great value, in my opinion.
Those are both 2-channel scopes, but for the work I do, that's usually enough.
