Oscilloscopes - what specs to look for?

Hi,

I'm gonna get me an oscilloscope. I'm going to use it to mainly fiddle with home audio equipment, like hifi amps, and perhaps try to fix this and that other electrical appliance. 

What should I make sure I've got covered?

Some say 50Mhz is good, others 100Mhz. I've also realized memory depth is important, but what is enough? I see oscilloscopes can easily top the overall price of my hifi system if I'd really want to.

I was considering an oscilloscope several years ago and during my research came across this guy.  First video is his feelings about the cheap PC based USB oscilloscope devices:

Here's his review on the Rigol DS1054Z:

The guy is very entertaining and the videos will help you with how these scopes are actually used.  I ended up not getting a scope, but in my reviews I was siding towards the Rigol models and would get a step up model, such as the DS2202A.  It's only 2 inputs, but a higher 2GS/s sampling rate.
