Hello all. New to the site.

I would like to put together some sort of rack/mixer/recording system for my home. Here's the basic idea:

I would like to be able to plug in a guitar, bass, mikes, and electronic drumset into one 'rack unit', be able to play live through monitors as well as record on my laptop. I would prefer the unit to be portable so I could run it through a cab as an amp head, if possible.

I have absolutely no sound equipment at this point. Here's one unit I found: http://www.musiciansfriend.com/product/Behringer-PMH1000-Europower-Powered-Mixer-?sku=631252

I like what this unit offers, but I would need a seperate rack system if I wanted to add other units. Cost is priority, I'm not looking for top-of-the-line.
