I’ve read a couple of Dean’s books and I don’t regret it, but also didn’t find them that good.
Outside a couple of disappointments, everything I’ve read from King has ranged from really good (Salems lot, tommyknockers, etc) to outstanding (the dark tower series, the tailsman).
I bought a 97 Ford Taurus off a friend for $800 back in 2008. Her dad thought it was on its last legs at 155k miles so he wanted to sell it. I drove it for four years. It was running fine until someone blasted it out in front of my girlfriend’s house and drove off. At the time it had 206k miles. 50k miles for $800 was certainly one of my best purchases.
