I do not know if TDS3034 is any better or not. But I do know that 
TDS3032 is one of the worst scopes that I ever used (no offence here).
We used to have a lot of HP (now Agilent) 54600Bs and some Tek 
TDS360s in the department and are still using some of them. They
are getting older, so we bought one HP 54622D, two Lecroy LT264 
(expensive), and quite some TDS3032. The two Lecroy are very good.
Some old Lecroys are also not too bad but we have problem servicing
them. The 54622D is quite good for MCU development but I would like
to have a 4-ch model and it does not belong to me. :(

The TDS3032 turned out to be the worst choice. Looks good on paper 
with the specifications (300Mhz 2.5GS/s) but the actual refreshment 
rate is even slower than the good old 54600B (100MHz). I do not know
the reason but maybe it is the lousy color LCD screen. I end up
using the old 54600B and borrow one old Lecroy sometimes for SMPS 
power supply evaluation. Now with next year's budget I am hoping
to get another Lecroy. But it is a bit expensive that we have to
sacrifice some other things.

The isolated TDS2000 sounds interesting though. However you can also use
battery powered scope or isolation transformer for SMPS evaluation.
Or you can use the dangerous method of removing the center pin of
the AC power plug (not recommended).
