There are alot of cams out there and you don't have to go with the most expensive cam to get the best pictures, as has been exhibited by Lucy's cam. I have been so tickled with the feed that I went out and bought one too. I can't have a computer in the barn at this point, but I have enjoyed playing with the cam.
And in defense of the link I have on Mare Stare to www.barncams.com, I promote things that I know work, and that I believe in. Bill at Barn Cams stands behind everything he sells. His cameras are a little pricey, but the quality is excellent and I've never heard any complaints from anyone on his service. I've had items that I've broken by dropping or mishandling and he's replaced them with no question and no charge. He has awesome customer service and I'm sure can give references if he's asked. You can't get that everywhere.
But again...there are extremely good quality cameras out there that won't break your bank account. I can only comment on the ones that I, or my customers have experience with. I do believe that you get what you pay for, but it doesn't always have to break you to do it.
Just make sure that you can return whatever you buy - if it doesn't work with your particular situation. :bgrin
