That's an insane amount - how old is the dryer?
I've replaced two heating elements in my ~9 year old Samsung dryer, I think the heating elements were less than 50 USD. I did the labor myself so I don't know how much that would have been - you do have to take the dryer apart, but it doesn't take very long if you have experience, 15-20 minutes or less.
I would not recommend Samsung - I've had to take that dryer apart more than 10 times to replace/fix things, I can't imagine how much it would have cost me if I couldn't do it myself. The only plus there is now I can literally break it down and put it back together very quickly when I need to fix it.
Luckily the Samsung washer has been fine.
