SONY CYBERSHOT DSCW55 7.2M
I bought a Sony recently -
It's a Sony Cybershot DSCW55 7.2M, available in Silver, Pink or Blue. I took it to Alaska recently and was absolutely delighted with the quality of the photos. It's not necessary to buy the Sony Memory Card, mine is a SanDisk 2 GB Ultra II Memory Card and works perfectly. My OH was so impressed with it that he ordered the same model from Pixmania. It has the 2.5" screen. He bought an extra charger which works from the car battery. When ordering you have to buy the battery separately. Pixmania do a nice case also, although I got the Sony one, which has a little pocket for a spare battery and additional memory stick. I have 440+ photos on it at the moment and the battery charge lasts for ages.
Very cool camera - easy to use and great photos - I love it. I used to be a member of a Photo Club and owned various SLR cameras, complete with zoom attachments, filters etc and can honestly say that these photos are comparable to anything I took in the past, with no hassle. You will see professional reviews online which go into the technicalities. I bought mine from amazon.com - the complete package, camera, 2 batteries, charger, card reader, case, 2 Gb memory stick, all came to around $305.00. I had it sent to a family member in the US and collected it on a visit there. However, Pixmania do a great deal also. I have seen some posts on this site complaining about their service but I can't complain. I bought a Sony camcorder from them recently - ordered on Friday lunchtime and it arrived on the following Tuesday.
Highly recommended - have fun!
