I'm get sick of my old memory card. I'll get about 50 pictures, and then the quality of the pictures go down. They get worse when I don't format the card, and just delete one by one. And it's not uncommon for me to take at least 100 pictures when I get the chance. My camera is a Panasonic Lumix DMC-TZ4. My current memory card is...well its old enough all I know is that it's blue, and I bought it about a day after I bought my blue er...Kodak, 2 or 3 years ago. Price isn't a problem, I just need a new memory card. Suggestions?
