I never really got on with those dip-in infuser things; I may have just had a duff one, but it always lost about half the leaves when trying to remove it. The teapots with a basket work fine, and possibly give the leaves more room to infuse; I like my tea strong, so these days I just make it in my trad brown teapot and use a strainer when pouring. For fancier use we've got a swanky Marimekko pot which looks lovely but isn't as good a pourer.

Looks like Argos are selling Bodum glass teapots cheap (£15) at the moment: http://www.argos.co.uk/product/6879417
