I will say always read the ratings of an item and don't buy 3 star or below, and watch the shipping costs.
Now infrared cameras for this monitor can be found for $44.00 each so if you get everything you save from
$100. 00 to $400.00

Another auction site that you can get great deals on all sorts of items
http://1800lastbid.com/ The only thing here is a lot of it is used and you have to pick it up. The main branch is in Byron Center next to Grand Rapids. I will say that the prices here have been going up as it gets more popular. I bought 10 computers from here for $6.00 a piece and they all worked. Lately the prices are higher, $20-$100 on average.
Another auction site that you can score a deal is
http://www.shopgoodwill.com/ This site the prices are going up lately too.
Hopefully I helped save some people some money.
