I got my sp3 in December, and have been, like a lot of you I'm sure, trying to justify the expense of the dock. I found a used one on amazon for $128. Used but with 30 day guarantee. Got $30 gift card for opening an amazon Visa card , applied that and my net cost is less than $100. I got it today, hooked it up, and all works flawlessly. This is a very well made piece of equipment. I was scared after all the bad things that have happened to some folks with this dock. If you are borderline, get it. My 2 cents.
