Need advice on 20D repair

I'm sending in my 20D body next week for repair. Have a 2nd 20D body now to use while it is gone. It does not AF anymore. Question is - since I know I have used it for more than 100,000 pix..... what else should I ask for - have them do now? Is there such a thing as an overhaul, refurbish? Should I ask for a new shutter or just let it ride so to speak. No, I do not have a lot of $ to spend but do need reliable cameras. OK, someone tell me not to even send it in and quick sell it on eBay as-is. Options please.

20D's actuation cycle is 100,000, so getting a new shutter might be prudent.

They'll thoroughly check it over and bring it back to spec. If that means a new shutter, they'll do that. You're still in warranty, anyhow. You could always identify some problem that would make them look more closely at the shutter while it's in.

You sure take a lot of pictures

Best regards,
Andy
