I've owned 4 Toshiba laptops (build my own desktops). The only major problems I've had is from the kids knocking them off the couch and shoving the powercord in breaking the peg off. Mine still works but had to get the wife a new one. mine is running hot for some reason, but I'm not sure what is going on.
Check Newegg (by far my first choice for comp parts) and Walmart/Best Buy. If you go in knowing what you are looking for at Best Buy, you wont get sold some POS that isn't worth the money.
