Morticer
 

Sedgwick morticer with a dozen or so chisels. All works. Three phase 415v motor which can be connected in delta to run on 230v three phase, so can be used with an inverter ( which is how I've run it for the last few years).
£250, buyer to collect ( I could deliver up to say 20 miles from Saffron Walden)
The cheapest I've seen this model advertised for is £450, but I need the space for a new mill!
