Portable Studio Setup, The best options for portable studio Options

[DEVIOUS]

I know that there are many discussions on this topic but I am still uncertain what is the best option for an affordable compact studio solution. I intend to use it for recording both 'real' instruments (guitar, vocals) and midi. I record a variety of different types of music but wish to concentrate on the more dancy/electronic type of music.

So far this is what I've come up with to add to my Powerbook G4:

Tascam US-122 (I only need 2 channels recording at once so I think USB should be ok)

Midiman Keystation Radium49 Keyboard (I need something I can actually play stuff on- can't accept the tiny keyboards. I intend to use portability only for the guitar and vocal recording)

Reason 2.5

A good all rounder microphone (does this exist? I want to be able to record both vocals and acoustic guitar through this)

I wish to later add Cubase Sx to this but currently money is of prime importance.

Does anyone have any alternatives or opinions on this?
Nearly all the posts tell people to spend more and more until it's all costing too much to be a hobby. I wish for quality like anyone else but don't expect to do more than neatly develop my ideas on this setup.

Any help is greatly appreciated.

Personnally, I am not a fan of Tascam products. Please check out the MBox by digidesign. For $400 you get the interface AND the software.

I have had terrific luck with the AKGC3000 as an all around mic for many applications. I use it with choruses for live sound, recording vox and guitar. They sell a package with the C1000 although I don't like that mic as much but it is a good starting place for the $. I have recently started using some of the Sennheiser mics and I like them very much but I haven't found an all around mic. See if you can go to a store and listen to them.

Good luck!
