Some of the Kodak cheapo camera's are rated by the digital camera magazines (yeah I read them when im in my dentist lol) as good as far more expensive alternative makes.
My mums old 3.2MP Kodak cam which ost her a measly £99 two years ago more then proves this, it trounces even modern day alternatives from the likes of Fuji for image quality and defenition. And of course Kodak's are almost always far superior at colour re-production.
The best value camera atm HAS to be the Kodak Z710, not only is a high end processing camera, with 7MP maximum resolution, but it has a SCHNEIDER-KREUZNACH 10x optical zoom lens - in the world of professional photography, Shneider are ranked way way above even the likes of Carl Ziess for the optics.
The z710's are going for around the £160 mark online, so there really isnt any point in going for a bog standard £100 camera, when you can get one with extremely high quality (near professional) optics for just a few quid more to be honest.
I am very interested in photography as a hobby, and have made good use of my mums Kodak for the last couple of years, but I will be getting a Z710 this summer. Oh and it also does VGA video recording, which is near DVD quality (640x480), most camera's can't record better then QCIF. Not exactly what I want from a camera, but its always an added bonus.
It takes SD cards, and with 2GB cards going for £10 online atm...
Don't be fooled by the megapixel war Stuy, a 10MP camera is very rarely better then a 3.2MP camera, most high pixel camera's use techniques like interpollation to increase their MP count anyway, which causes reductions in overall image quality.
Unless you want to take photo's and print them as posters, then you will never need to be taking more then 3MP shots.
Concentrate on the quality of the optics rather then the megapixel count, its just a number that brands are ramming at the consumer to sell camera's.
The future of digital camera's is actually 1 and 2MP cams that will far outdo the high MP jobs of today, due to their ultra efficiency. ATM manufacuter's make cams that do 5 - 10MP, but around 90% of the pixel are actually wasted due to the way they work and the low quality of the optics and processing.
