I don't mind the UI on the older ones myself.

I've not had any problems with using them with VT100 codes, but they 
don't work that great emulating a VT220 or VT320.

Does the VT420 have the same speed issue?

Nope.  ASCII and RS-232/RS-422.

I guess I could be called an "IBM shop", but I used to have a 
combination of VT320s and VT340s.  Now I have VT420s and VT340s.

Me too.  But I'm interesting in getting a load of terminals with better 
keyboards.  I can't tolerate the LK201.  The LK401 was better, but IBM's 
terminal keyboards are a giant leap upwards for me.

Yes.  Page-oriented.  I doubt it's possible, but on the off chance, I'd 
like to use it that way.
