Bart,
You would likely be pretty happy with a lot of "generic" mp3 players if you shop for features rather than name brands. I used to have an iRiver MP3/CD Player that was GREAT and I wouldn't hesitate to purchase another iRiver product (if I were in the market) because they tend to offer more whiz-bang features for your hard earned dollar. They are based out of Korea.
Now I have a Rio "Cali" and what you describe is exactly how I use it. I never use the bundled software, and have never really decided on a player for my PC - what i need is quick and dirty drag and drop capability from windows explorer and NO DRM. The "Cali" model is pretty durable - I wouldn't hesitate to drop it two stories onto concrete and I suspect it would suffer little more than a cosmetic ding - try THAT with a iPod.
The biggest thing that sold me on the Cali is that it has an SD Card reader, so i never have to worry about filling it up - I just keep a handful of cards around with different selections of music - and you can use a variety of readers to drop music on the card so you don't even have to plug in your MP3 player to organize your music collection.
The only thing better than an MP3 player with an SD slot, IMO, MIGHT be an MP3 player with a big hard drive built in, but it would never be as durable as my Cali, and it would cost A LOT more. I got mine at Best Buy about 2 years ago for about $120.
