Monitors galore....!

Well ive decided to get rid of the bulky 17" CRT monitor and swap it for a nice spanking new 19" TFT.
But whilst on my mission to find the best offer i came accross something.
Where it says something like 16ms and 500:1, does the ms need to be higher for better quality or lower and what the 'heck is the "500:1" malarky!?
Thanks for any help friends, and the webpage i used is here; http://www.ebuyer.com/customer/products ... at_uid=354
