[TenTec] OT: Scopes

[Hulett, Russell]

I've avoided owning a scope, but the recent discussion about troubleshooting low power from an Omni D has me rethinking.  Most of the gear I own now old, have managed to diagnose problems without owning a scope.  In one case, the problem with an old hollow-state receiver was found by poking around with a wooden dowel to expose a poor solder joint.  My main concern is spending more money on a scope than my shack is worth, or alternately spending more time fixing a used scope than is warranted.  

Would be curious about thoghts from others who repair their own gear about what minimum-required scope would be.
