In this case, the Apilus represents better value for your purposes. You don’t need to be spending thousands on a machine with all this functionality you’ll probably never use.
Insulated probes are not suitable for galvanic, but I doubt you’ll spend much time using galvanic due to how slow it is.
It definitely looks a bit used and dirty, but what matters is whether or not everything works internally. When buying older machines, it’s difficult to know how much support you’ll find if something breaks. Not having access to a manual can also be a concern.
If you have concerns about the Apilus, it’s better to avoid buying it and wait for something else to come along. I still wouldn’t bother with the Clareblend though. At that price, it doesn’t make sense for you.
