Yes, 100 Mhz is good enough. Even 50 Mhz scope is OK for arcade/console repair. After all you'll never worry about scientifically accurate measurements. You just want to detect a signal's presence (and shape of it) in arcade repair, not designing the circuit from scratch
Regarding channels. Yes, 2 ch is enough. I barely use the second channel anyway. Used only a few times to compare a timing/delay of two signals.
If you don't want to invest too much, a second hand Tektronix will be an excellent tool for the job, if it is working fine
Just keep in mind, the probes are sometimes more important than the scope itself. You'll be frustrated if the probes are faulty. So better make sure the probes are OK...Well I finally got around to picking up a few scopes. Deal was just to good to pass up. I got a tek 466 for 50 Cad and a day later a lightly use Rigol 1054Z for 300 Cad. Craigslist browsing at midnight can have its benefit. Now I just have to find time to learn how to use them. How does one test the probs? A few of the one that can with the tek 466 have no real marking. Data sheet my best bet?

Best way to test the probes is to use the built in test voltage, there will be a point on the front panel for exactly that.
It produces a square wave signal so you can calibrate the scope and confirm your probes work correctly
Source: I have a Tek scope myself, great piece of gear
