Is this a good monitor (hdtv) to connect my MBP to??

If $400 is your price point you would be much better off with the Viore 32". The main problem with the TV you chose is it has quite a low resolution at 720P (likely 1366x768). While the Viore is 1080P (1920x1080) so will prove much better as a computer screen as the text and images will have much finer detail. The Viore will also provide better HD images due to its finer resolution.

Though I could not attest to the overall picture quality of the Viore. For cheap TV's I have found Insignia to be a good brand, this Insignia 32" runs $450 currently.

 

I agree. 720 is a good resolution for a TV of that size but not so great for a computer monitor. Because you will sit closer to the screen when using it as a monitor the decrease in resolution will be more apparent. I would go with something 1080p or better for a screen that large.
