Maximum PC

Need an approximate appraisal on my Samsung Galaxy Tab 10.1 32GB (Metalic gray)

It comes with a carrying case / folio case, HDMI and USB adapaters, and original box and materials. Excellent condition (barely used, but about 6 months old).
I guess Verizon still sells them for $600 with plans. The galaxy Tab 2 - 10.1 " 16GB goes for $400 without the extra stuff I have (if this helps any).
My tablet still only has Android 3.2 HOneycomb, but it can be upgraded to ICS 4.0.

Ideas? I'm going to try Craigslist first, and then if that doesn't succeed, then I guess I'll go eBay.

Try Gazelle for the device, eBay for the rest. Craig's would really interest someone soon with all the gear for about $300. The Nexus7 really screwed up the market for tabs lately. I literally can't sell a G1 Transformer & Keyboard for the cost to purchase a Nexus 7 currently.

That's tech dude, magnified. Pads are new and aren't even aged a bit before they're old. I fear that as people grow aware of how niche they are the prices drop more. Kindle Fire's are still sold for $200 new on Amazon. Huge phones are imploding and tabs are shrinking back to reality (4.3"/7"). They're figuring it out!

odd
I really like my transformer prime tablet (and yeah keyboard, I had to have the darn thing)
but its pretty nice for extra battery life
