I can't comment for the Hisense model you are talking about, but there are fundamental differences in the cooling technology between some of the lower spec/cost cabinets mentioned earlier and the Vintec/Transtherm designs. This is the main difference in cost.
There is a bit of material on the web about the pro's/cons of the different types, I researched it all a few years ago but have forgotten all the detail now.
I ended up with a 120ish bottle Vintec (as other say the real capacity is smaller), which unfortunately had a refrigerant leak in the first six months that was repaired under warranty within a few days. The service technician lives around the corner from me which is helpful (also does A/C's), he does past warranty repairs for other cabinet owners in the Brisbane area so the back up service is pretty good. Over 3 years old now and no other problems.
If you join the Vintec club there are occasional invitations to events.
