iDect
iDect/Binatone - look shiny but, as I've previously found to my cost, the build quality is shite; had an iDect once that wasn't particularly cheap and looked fairly awesome (oki, for a landline phone) ... after about a month you had to dock it into the cradle _just_ right or it wouldn't charge - eventually resorting to bits of broken matchstick or folded paper to try and get the angle right before thinking "you know what, this is a joke" and forking out for a cheap, ugly Panasonic instead ... which has worked perfectly ever since.
So the rule of thumb, I guess, is - if it says Binatone avoid it like the plague.
