Multi track question

[ghostly neutrino]

Hi,

Am searching to buy an inexpensive, but decent multi track to record my noodlings on my MS20. The last time I was around a multi track, a friend was commandeering it and all our sounds were spat into a...cassette tape master! Yep like 25 or so years ago. I knew pretty much squat about the technology then, and now even less so with interface with a computer.

There's aTascam DP-03SD 8-Channel Digital Portastudio, and there's a Zoom R8 Multi-Track SD Recorder that a guy I was studying synth with recommended.
I know the Zoom R8 is out of production, but I heard good things about it. In both of these cases the price point is right for me.
I'd be glad to hear your opinions...or about any other multi track within the price range or cheaper.
I have a modest Behringer mixer.
I'm not looking for the big time, but a good time with something decent.
My sons laugh and say why don't I just use garage band? Well, no one who is of my generation thinks garage band is any answer. But why? I don't like virtual things anyway, so a dedicated multi track is what I'm after. But am I spending money needlessly? What makes a dedicated three dimensional multi track desirable?
Another thing, I have a Mac Airbook of some 4 years or so vintage. Would it be receptive?

Thanks in advance...sorry for the zillions of questions.

The Tascam DP-008 is a nice machine. Portable, with built in high quality mics for ambient binaural-type outdoors recordings, it records two tracks or a stereo pair at a time. If a greater simultaneous track recording capability is required, the Zoom R16 does up to 8 tracks simultaneously, but is somewhat larger.

For old school, there's the Tascam Porta-One.
