You beat me to it, RichardH - I got one of these at £9.99 last time around and am very pleased with it for the cash. Worth spending the extra fiver for a packet of extra bits for it, too, IMO.
Off topic, but I noticed in the latest Maplin offers catalogue that they have a butane gas torch which runs from a disposable lighter for only £4.99 - would these, does anyone know, be suitable for heatshrinking purposes?
Cheers...
