pick a spot on the picture, maybe 1/20th of the image. Crop that at full size and upload it, hopefully with 0 compression etc. It's like asking us to compare how a cd sounds with 128k mp3s

if it seems like a good price, and you are looking for that, then buy it
if it doesn't seem like a good price, and you're looking for that, buy something else
if it doesn't seem like a good price, and you're not looking for that, stfu
