Well, I love my Dualit. It replaced a Briel Due killed off by London's hard water (tip - use cheap spring water). I did toy with the idea of getting a La Pavoni or Elektra manual machine, but I couldn't be bothered with the faff in the mornings. I've been told by mates that have bought them that some of the cheaper Gaggia machines have quality control issues - buttons falling off, that sort of thing.
(edit: yes, stovetop mokas are great things. kept me going when the Briel karked it. I always forget to clean it though, leading to new forms of life being discovered in the cupboard six months later.)
