Treadmill info/help?

Hi guys. I'm looking to purchase a tradmill and wanted to get your thought on this one as well as things I should look for to ensure i don't get crap.
btw: any sites where they "rate" treadmills based on statistics, reputaion, etc??

Thanks in advance!

led display, 0-10 mph quick speed control, 6 built in "workouts",18x50 treadbelt and 2.5 hp

reg - $800.00

sale - $500.00

after reading reviews I don't think it's a good bargain.
