Having just bought a Digitech RP-6 in the last couple of weeks, I'd agree with this recommendation (and I only paid £50.00). Once I got my head around the editing of patches I've found it very easy to use. The effects are spot on and even the overdrives are good.
I've started programming a patch in with whatever effect I want (a delay for example), but also have the chorus/flange/phase set so it's usable within the song the patch is programmed for, same with the overdrive. When you save the patch, just have it saved so only the delay comes on, then you can easily manually knock on/off the other effects.
If you imagine this for half a dozen patches, you can soon cover a very wide amount of tonal ground. I'm also digging how the wet/dry levels for things like chorus, flange, phase and such can be set to taste. I'm not massive on how many modulation effects take over your tone and always want more of the dry signal.
Plus, with the patch levels you can very easily set up a dramatic lead boost in volume.
It's been a long time since I've dabbled with multi effects (Zoom 9000, the grey space-ship one, was my last real one ) and the quality of them now is a million miles better than I thought they would be. Plus thats considering my RP-6 is a few years old already, so the newer ones are likely even better - I know the TC Nova System is very nice indeed if we're talking of newer multi-effects units.
Since the OP is headed to Uni, a used multi-effects like the RP-6 would offer great value for money and could be incorporated into a gigging setup at a later date.
