Even a moderate priced Windows PC and audio interface will easily cost more than a stand alone Multi-track recorder.
That's possible, I haven't looked at the all in one multi-tracks recently. I remember the one I had .... editing was a real PITA....
I'd say save the money until you have enough to buy a Windows computer and an interface. Software for the DAW is available for $20 so that's the least of the cost.... editing on a software windows based DAW is so easy to do....
