I’ve been through a few for exactly the same reason, bog all space in an 1890s galley kitchen. Despite spending a lot of money I failed to find one that didn’t have all the worst features of a washing machine combined with all the worst features of a tumble drier. Separate machines are night & day better. If I had to go back to a single machine I’d buy the cheapest I could find, reassured by the knowledge that at least it’d be cheap crap rather than expensive crap.
Something like Bosch or Miele might actually be decent, I don’t know, but I can only imagine how many kidneys you’d need to sell first.
