Looking to upgrade our software/hardware at our church. We are smaller so do not have a huge budget for a new one - any ideas on where to get a older, iMac or MacBook Pro to run our presentation software. Ideally I'd like to buy a 2011 model or newer. I've tried eBay, Craigslist, etc but nothing in our price range that's reasonable. I'd ideally like to find a large church that's looking to upgrade their hardware that we can purchase from OR someone looking to donate old hardware to charity. We'd be more than happy to provide the person a tax write-off for the purchase. Any ideas? Or should we just save more and buy a new/rebfurbished unit from Apple?
