George,
While I'm not really for the idea of trashing perfectly good, repairable washers that other people can use, there are washers out there that are in such horrible shape, you wouldn't even be able to give them away.
An excellent example are washers which are so badly rusted that they're either unsafe to people, unsafe to clothing or just in such a poor shape it's not worth it to fix.
In other instances, when the bearing on a front loader goes and it is out of warranty, it can cost more to fix it than what the washer is worth... and it's not viable to give it to someone either. (I'm sure they wouldn't appreciate hearing a freight train coming out of their wash area whenever it went into spin.)
In which case, destroying these washers already bound for the junkyard is in some ways, good entertainment and a good stress reliever, provided it's done properly.
Now, in saying that, A brand new Roper or Plastic Tubbed GE washer is $300. I've also seen plenty of washers selling on Craigslist and Kijiji which are in great shape for even less than that. Heck, I sold my top of the line washer/dryer GE set for $200, how much cheaper can one get?
What I don't advocate is going out and buying brand new washing machines and then trashing them. Unless you are rich and you just don't care what other people think! (The exception to this are LG top loaders, but that's a whole other story.)
