As memory sticks go I think they have all become very cheap. I tend to use Kingston RAM and Mem Sticks as they have a life time warranty and only cost a few pounds more to buy, although retailers do charge more as they have a good name. Go to e buyer you will probably get one there, buy as big as you can afford, although as previous answer said you will probably only use part of its capacity. One thing is certain they are the best gadget for a PC and really usefull. One last thing, if you have USB port on your photo frame it will plug into your PC USB port so you can drag and drop into the frame.
