If I had to choose ONE 7xxx series 'scope to have, it would be the 7904A. All of other variants mentioned are excellent examples of the basic 7xxx 'scope implementation, but the 7904A is the best all-around 'scope to own. I used one for many years when I was working for StorageTek and was lucky enough to have a private lab where I could keep the probes and? plug-ins from being stolen and messed up.
I have a 7104, 7904A, 7934, 7854 and 7623A. All of these except the 7904A have features that need to be understood in order to use them effectively, and the additional features above and beyond the features of the 7904A are usually ones that I rarely need.
Make sure, though, that if you buy a 7904 it is a 7904A and not a 7904. While the 7094 is also a good 'scope, maintenance on it is a bit more difficult because it does not feature the "kickstand" that most of the other 7xxx 'scopes have, where one can split the 'scope and raise the upper section off of the lower section and engage the kickstand to hold the two sections apart when one is servicing the 'scope.

Hi Tekscopes,
Here in a couple of months, if all goes well, I'm going to have more lab space, and more importantly, more bench space! I've always wanted a Tek 7000 series scope to add to my (mostly HP with one Tek 2465B) boat anchor collection. I've looked at quite a bit of information online. Seems like one of the most sought after is the 7104 with the microchannel plate CRT. Neat box, but I'm aware of the special care that needs to be given to those CRTs (and that it might be hard to find one that isn't worn out already).
I know I want one with 4 plugin bays for maximum flexibility. What model should I keep an eye out for? I am fully aware that it might turn into a project, but that's fine so long as it's repairable and not filled with unobtainium parts.
Thanks!
Sean
