Not too bad, considering the space it sits in.
Another "physical modeling synthesizer" which I've been looking at for the last few weeks (https://www.ericasynths.lv/steampipe-3153/) goes for €990, which is more or less the same as the phase8, when you consider the currency difference.
Edit: Actually, seems phase8 will be slightly cheaper, my local (Spain) shops seems to sell it for around €950.
I really love the Steampipe and its approach to synthesis, its a lot of fun:

Erica synths makes really solid hardware too.
