Guitar Rack effects

[sist_si]

Hi guys,
I've recently got myself a new rack tuner and i'm going to get a rack case to house it in.
I also want to expand my effects a little bit so I'm looking to get a rack effects unit (with pedal board). Primarily, I want to be able to set up different clean sounds on there while still using my marshall distortion.

At the moment, my clean sound is basically my marshall JCM2000 head with a tiny bit of overdrive on the 'crunch' channel with a little bit of compression and chorus on an external pedal. It's this I'll want to recreate to start with.
I also have a boss delay pedal so that will be another effect I'll need to create.

Anyway, can anyone recommend a reasonably priced rack unit that would loop through my amp head? Is this possible with the 'effects loop'? I'm not too much of a tech head when it comes to this.

That just went stright over my head Andelusion! haha.
If I got myself one of your suggestions, could that be rigged up to replace my current clean sound (compression, chorus alongside my Marshall head) but also have foot switches available to select things like delay/whatever?
For my distortion channel, I'm gonna stick with the marshall but essentially I want to have my 'clean setup' running underneath everything if you see what i mean.

I reckon I could stretch to £250...was gonna look at 2nd hand maybe.

cheers for your help Andelusion.
ok, sounds like i'll have to do a bit of research. I might pop into my local music shop and see if they'll show me whats what. I'll get a better idea if i can see how it'll all work.
I think ideally i do just want to colour my basic clean sound and then just switch between clean and distortion on my marshall but it'd be great to be able to replace other external effects such as delay in the one unit as well and switch between those (while always having my basic clean setup there)
