I have two iPod Video (5th Gen)

One has a bad battery, the other a bad screen.

I found ifixipodsfast/com, but the parts are expensive compared to ones on eBay

580 mAh

650 mAh

900 mAh

What difference does the mAh make, and does it make a difference which one I get?

Also, the screen

Brighter

Should I get the brighter screen?

(I am sorry if this post shows up multiple times, I have posted it twice, but it never appeared)

When I've ever had to by spares for my iPod I used http://www.repairsuniverse.com. Reasonably priced and a lot more professional and quicker than ebay. Always been very helpful and shipped quickly. Hope this helps!
