Buy a new charger for T410i

[qbektrix]

My laptop is a T410i 2518-J3G. I lost my charger and I am in New York.

When I checked with IBM & Lenovo, I was told that the part I needed was a 65w charger (Part no. 42T5283). But was out of stock. So, I want to buy a new charger. Any suggestions, I am hesitant to buy one off amazon as I not sure if it will damage my laptop. Could someone please suggest me a trusted 3rd party vendor or provide me the link to a charger that I can buy.
FYI: I lost the cable and the adapter (the part goes in the wall & the laptop.)
