Pagman: if your computer can run it try downloading the Lightroom 5 beta from Adobe. I use a 20D and used iPhoto until the logic board on my macbook died and then I got an i5 windows8 laptop and tried the the LR4 trial. It took a little adjustment but it did more than iphoto so I bought the full version and haven't repaired my macbook. It might be worth it to buy lightroom and use that for a little bit until you can save enough money to get a new cam or lens. I'm not gonna upgrade to LR5 because I'd rather get an SSD for my laptop instead.
