It's well known that, due to how the market flows, older technology will become cheaper over time. In the field of memory, prices have been dropping lower and lower for quite some time. Newer products such as the 16gb memory stick pro duo have dropped prices considerably for lower capacity memory cards. The question you have to ask yourself is… well… "just exactly WHAT does 'lower capacity' mean anyways!? Consider this. If you bought a 1gb memory stick pro duo in 2005, in the months after the PSP was released, you would have been shelling out anywhere from $85-130. I personally paid $92 for a 1gb card back then. Of course, I knew prices would drop, but wow. While looking over prices at a non- affiliated and very much unrelated website, Newegg.com, I was able to find 8gb memory stick pro duo cards for $54.99. The 4gb models are definitely a bargain! If you're in the market for memory, the time for you to buy might just be right now! For the price I paid for 1gb 3 years ago, I can pretty much get 16gb worth of space today. Memory prices are on the cheap, so if you need the space, it's affordable. At such low prices, you really can't go wrong. Get it and game!
