Hello, My mom is visiting me in a couple weeks and we don't really have a desktop computer at home, I always take my computer to work so she wouldn't have anything while staying with us. I noticed there are iMacs for sale under $200 on ebay. They are old computers from 2007 and 2009, but all I need is a devices for internet browsing and youtube videos probably. She gets online just to keep in touch with family. Do you think $150 for a 2007 iMac is a good buy?
