i see nothing wrong with your machine as starter or backup machine later ...
It basically holds two 1400w motors and a 160 psi pump ... it sucks and squirts like all the rest , as long as it isn't leaking or falling apart i dont see much reason to part with it for the time being ...
weren't these selling for about 600 on e-bay ? cant go wrong there , and vacs can be £50 to replace whenever need be

I believe they make a version with a 2000 heater (GMC-3H) if you have no heat , i would spend 400 or so on an inline heater ...
what you have then i know i could do basic work with ... the victor for either agitation , pre or post bonneting , occasional LM jobs ... the sebo , and your twin vac .
I would get an inlineheater and a couple of airmovers next , and a new machine when ever you can afford it .
