Replacing Linksys PAP2's AC adapter

With Vonage, I have a little phone router called the PAP2 from Linksys. It uses a 5V 2A AC adapter whose tip's polarity is positive. Through the tragedy of moving internationally, I have lost the original adapter. I have sought high and low for a replacement. To make a long story short, in Canada, I can go to The Source (formerly Radioshack) and if you go to the digital camera section instead of the AC adapter section, you can find the one adapter that will fit your needs. 2000mA, with voltages at 3, 5, 6, 6.4, 7 and 7.5V DC. I'll note that none of the plugs are the right fit, so you might have to spend another 3CAD on a K-type plug tip.
