560x Battery

[gadiyar]

Hi,
I need a new battery for my near antique 560x. What do you think is my best bet - eBay or some other stores. It's available on ebay for about 50 dollars including shipping. For example,

Ebay Link

Else, other stores on the net are upwards of 70 dollars. Eg.

What others can you recommend?

Thanks in advance,
