the HV20,30 and 40 'consumer grade' camcorders are rated pretty highly iirc, and are pretty reasonable, and have a decent amount of manual controls. Check out

There are alternatives out there, however - there's some cool sony ones that are basically mini versions of the hugely popular Z1 - I'll try to dig out a link. edit: Sony HDR-HC1E. There's also a 'pro' version that has an XLR block, but that's about where the differences end... the HC1E is the one of the two to get. But they're still expensive, and probably not significantly better than most other high-ish end consumer HD camcorders.
One thing I'd strongly reccomend for shooting fireworks is to get a wide angle adapter, especially if you have 2 cameras, put the wide angle adapter on the 'wide shot' camera (locked off on a tripod), and then use the other camera for 'closeups' of the fireworks exploding.
A camcorder with a LANC socket, and a handle mounted zoom control might be useful and help you to get slow smooth zooms with still getting the stability (rather than having one hand on the camera to do the zoom, which can make it shake a bit with lighter cameras). If the camera doesn't have this, get a £2 optical audio cable and tape the remote control to the handle of the tripod, with the LED on the top of the remote control pointing down the optical cable, and the other end of the optical cable to the sensor on the camera.
Sound wise, unless it's REALLY windy you shouldn't have any issues with just using a camera mounted rode video mic or similar.
Dont forget to budget in fluid head tripods, hard drive storage, etc.
this tripod will hold a camcorder like this happily and is pretty highly rated.
I will be too busy to do that as well Graham,thanks anyway.
Thanks for that mate.
No I don`t have money to throw about,alas...........
Any recommendations on what you call "half decent" camcorders.Budget about £1500 max?
