Is the HP 1745 a good'un then?  I have had a 1745, with two TEK P6131 10X
passive probes for a few years, but was unable to find a manual for 
it when first
bought it, and have not tried for a while now.  Never used a scope enough to
even know HOW to use one, but enjoy reading postings from you particularly,
along with a few of the other guys that seem to know what they are 
talking about.
I have been a big fan of Ten Tec for a lotta years, and have a stable 
of 7 of their
rigs dating from the Omni VI Option 3, back thru the Triton IV 
digital.  I am also a
big fan of Elecraft, and built the K2 #317 and K3 # 833.

Appreciate your opinion on the 1745.

Thanks,  73  Dub K5DUB
