I have recently surveyed and purchased a logic analyser in the U.K.
The H-P 1630D came out as best value for money (about 9000pounds including
tape system and a selection of disassemblers).
It is very easy to use.
Links with a storage scope to capture and display  a waveform during a trace.
Could be used with a micro for data collection & external control via the 
488 bus (we havent tried this).
The 'personality' modules for interfacing to specific cpus are very expensive
but could be attractive in a commercial environment - we intend to build our
own. Hooking up via the spring clips is ok but not wonderful - lack of
insulation on the probe body is a mystery.
A big plus is the availability this summer (it had better be !) of an internal
expansion board to give a total of 63 state channels - 25MHz of which 16 can be
used for timing - 100MHz.
Glitch detection (on the timing channels by halving the number available) is 
useful and anythig similar on the opposition cost a lot more.

Now someone tell me that I made the wrong choice and should have bought brand X
with twice the goodies for half the money.
