I recently purchased an 47" Insigia 120hz hdtv from Best Buy, I payed $700 for it, but now I see?

a HDTV in Walmart a 55" Pro Scan HDTV 1080p with 240hz refresh rate for only $200 more, are Pro Scan HDTV's any good or should I just stay with the Insignia model, I want to get the best bang for the buck and I will not buy an overpriced tv with the same features as the tv's I mentioned
