Just snag that first one i linked... it's $8. Double check with the the outer diameter of the plug though.. the inner is correct but they don't list the OD.

Tony, i've got one of the PS -131's they used to carry right here and it's 13V 1A. It's hooked up to my dock... works fine with my 2 drive empeg. So that one i linked would be more than enough.
