Someone is fond of the word 'like' LOL
But I have to agree. If you're not sure what killed it, you should find out first. Being that it died only a few hours ago, you should see if you can get a necropsy done.
And to answer the price question, I've seen them as low as $40 (mainly imports) and as high as $100 lately. I think $60-$80 is the general asking price.
