Well, the topic has been well covered, but I can offer a bit more
from a less-experienced point of view.
I own a TDS2002 scope, that's 60Mhz, 2 traces, and a color screen.
Before this I only had "trash" scopes pulled from other peoples 
garbage cans.
The TDS2002 is a big improvement (I should hope so!) from the old
junk I used to use. Yes, triggereing is "different" now. It seems
to take a fair bit of my time to get the display I want to see.
I never had this trouble with analog scopes.. But I'm quite happy
with the difference.
Advantages: I really like having different colors for the two traces.
The size and weight of the unit make a HUGE difference in usability.
I just use a padded laptop shoulder-bag as a carrying case, it works
out just fine. I'm not afraid to keep this thing in the trunk of my
car, which makes it a lot more likely to have it on-hand when I need 
it. The supplied probes seem a bit lightweight, but they are working 
fine. I also spent a bit extra for the communications module that has
a Compact Flash slot. Very handy for screen grabs.
Another big plus over analog: A wide variety of measurements can be
called up from the scope. easily measure pulse width, frequency,
voltage etc from the front panel.

It will take a bit more practice to get the most from this scope, but
I have no regrets at all. I can't compare it to other models available,
but I'm happy with the choice I made.
