do a drwa test. hook up a multimeter in series with the battery and see how many amps are being pulled. then start pulling fuses untill the draw goes away then once you have found what fuse makes the draw go away then you can start tracing down components that run off that fuse and see what is staying on to cause the draw. i'd look towards any climate control, cruise control, or any aftermarket items that may have been installed on the car: radio, security alam, radar detectors. i don't think the cigarette lighter are powered when the key is off but if anything is jammed down in them and they are still hot when the key is off that could also be something to look at. oh yeah or sticky switches or buttons like the door locks.
terrible one

On a rare occasion, it could also be that your new battery is a dud. For starters you should take it down to Autozone and get it tested.

Along the lines of what bryan said.. when I had this problem I ran a test light between the battery and battery cable. Pulled fuses until it went out. It ended up being the trunk light.

thanks guys!, this car seems to be teaching me loads!!, and you lot! :)
The trunk light is the most common cause for this. The trunk lights are activated by a small capsule full of mercury that makes contact as the light changes position when the truck is opened. The mercury inside the capsules gets dirty over the years and shorts out thereby keeping the light on.
A test light is a dang good battery draw tool. As stated above, put it inline bweteen the battery cable and the battery and start working the fuse block
Good luck
