Help in choosing an OScope

So, Having been in electronics for over 20 years I have never had the need for an OScope.I think it is time I purchase one and start learning to use it. I build and repair computers and sell and install CCTV equipment. My hobby is everything electronics My question is, what should I look for? Nothing I work on is high voltage. I just need to know what would be best for me as far as how many channelsand which Hz I would need. I see the majority on EBay are Tektronics.Thanks for the help.

I am looking at the one listed below. Please advise if you think it is a good one to start with or not.

Hitachi v212 20MHz 2 channel wavelength oscilloscope

EDIT: Would I be better off just buying a Prop Scope?

    That's a blast from the past :) - Take a look at DSO201 and DSO203 for a couple of price points (and much smaller).

    Yea, After browsing around on EBay I came across several of those. Are they any good? Can it be connected to PC and run through it and if so is software included?

    The EEV blog is a lot of fun! For modest use I'd pickup one of those low cost R1gols, like the one I have or similar. Unless you really need an Analog scope, go digital.

    How??
    Many moons ago I was brewing up ram cards and interfacing to PC pci bus and nothing worked until I borrowed a scope and was able to look 'inside' the circuit to see where I was going wrong. So I went right out and got a second-hand Tektrronix 456B. Cost a lot even second hand but I think I can say hand on heart EVERYTHING I have designed since I was able to get going- or at least know WHY it would never work.
    Go for it.
    Ah but what speed? (or bandwidth)
    Therein lies the question, with the new P2 going at the speed of light will the scope capture a 5ns strobe or pulse?
    These days you can get quite a decent box with probes that plugs into usb port on PC and can capture and store signals for later analisys - its what I am thinking of getting, but not having used one and not knowing anyone with one, first hand information is hard for me to find.
    Anyone else got any thoughts? particularly on whether these PC scopes are fast enough yet?
