Yes, and they also make some oddball scopes, scopes with plugins, and other
oddities. There are other things I wouldn't recommend buying unless you know
what you are doing. The OP is buying his first scope. He doesn't need to
wind up with something he can't use.

They all look good to me. I already have 7 scopes (seriously) but if I was
looking for a scope I'd consider any of them.

Dual beam is very nice. A delay system on the sweep is very nice. Some of
the fancier ones have a time / voltage digital measuring system built in -
also very nice.

If I were buying, first choice would be the one you listed second (even
though it looks like it doesn't come with scope probes). Second choice would
be the one you listed third. Last choice would be the one you listed first.

They are all fine 'scopes. The 465 is the best
of those (bandwidth > 100 mhz), but also the oldest
and heaviest, if that matters to you.

Note that probes are not a cheap item even on eBay.

None of the scopes shown have dual beam.

You got that right! If the Op can't afford to get probes, then that scope is
out. But, if he can, that scope would more than likely fill his needs, down
the road (if he gets more into electronics).

All emulate it with a dual trace system.

But what you say is irrelevant. He also doesn't seem interested in a whiny
nobody who adds nothing of value to any conversation.

Since I offer no email address that is self evident.

There is a list of HP and Tek scoes as long as your arm that are
perfectly "normal" and usable for a beginner.

As I pointed out in my other post somewhere, digital scopes are
usually NOT one of these, regardless of the brand. Nothing inherently
wrong with a plug-in scope. Any general purpose analog oscilloscope is
what the OP needs.

Telling a beginner to avoid HP and Tek scopes outright must rank right
up there on the dumb post of the year award.

No, your post won that one.

Post a list of the ones that are OK and the ones that are not OK to buy if
you are buying your first scope and know nothing about them.

What does he do if he buys one that needs plugins and can't find them?

How about you post a list of ones that aren't OK first?

Oh gee, let me guess, umm, he doesn't buy it in the first place?
The OP should already be getting the gist of this now, so shouldn't be
rushing out and buy some big hunking old Tek with empty slots.
Just your stand dual channel 20MHz+ CRO with the basic knobs is all he
needs.

Dave :)

Yep on all 3 of those Kit.
The 2213 or 2215 is probably slightly easier to use than the 465.
Nothing fancy to confuse you, this is what you want, a nice basic dual
channel analog oscilloscope.
Buy one and enjoy!

Dave :)

No, he buys it and realizes the problem when it arrives.

Which covers almost everything EXCEPT HP and Tek.

Oh really?
What about those three Tek's the OP gaves links for on eBay?
They look like normal dual channel analog scopes to me.
Even you said they were ok.
MANY other manufacturers also have wierdo scopes of one kind or
another that could confuse a beginner.
Almost any digital scope design from any manufacturer before the
current crop of "analog operation like" DSO's fits that bill.

Dave :)

My advice to a first time buyer was valid.

Clearly the OP is NOT buying one of these on his own, but on recommendations
from those here who have looked at the choices on eBay.

Your argument is stupid. Go away.
