PSP's help plsssssssss????

ok there is only one brand and that is Sony, there is the old fat Model and the new slim model, the fat is more durable than the slim, and not much difference, they are about $160 USD or $200 in a bundle...pictures go to gamestop.com, or even sony.com...yes all PSP's have the internet, but you'll need a wireless router to connect the PSP to. or any WIFI that is near where you are using your PSP...if there is anything else just let me know...good luck
