and you should also consider looking a bit south of the Danish border (e.g. Hamburg or Lübeck).

Actually you might even consider London. A relative of mine purchased all manner of items (furnishings, machinery, tools) at cut rate prices and had them shipped cheaply to Sri Lanka and Australia). There should be lots of used lab furniture coming on the market in anticipation of Brexit.
