I have a Nook color (which is a slower Android system) to which I want to download Slingbox for tablets. I’ve been informed I can only purchase this app from Android Market Place not Google Play. Can you assist me in doing this?
Android Market Place is technically just old version of Google Play, so I was kind of surprised hearing what you said in your question. However, Slingbox is available in Google Play, it is known as SlingPlayer for Tablets. The link is https://play.google.com/store/apps/details?id=com.slingmedia.slingPlayerTablet&hl=en
However the apps may not show up in Google Play on your device, if it is incompatible with your device.

I'm not sure if you're asking for a place to download it illegally or not, but Slingbox for tablets is definitely available via the Google Play store. Here's a link. It is a paid app. ($14.99)
