Does anyone have any input on the GS2000 wireless Bridge I found on RadioLabs.com

Looking into wirelessly extending my network out to about a mile and a half to where our shop is (Bins/Machinery/Hog house/etc). We have a 4 camera security system there that I'm wanting to view via PC from the house and also allow for wireless internet at the shop location so we can check email and browse the internet from there.

Internet connectivity is located at the house. As-is the Linksys DHCP router.
1.5 miles away is the shop/bins/hog house with the security system I want to view via IP browser.Line of site is no problem. I can see the bins with no problems at all from the roof of my house with all leaves on and corn planted between.

Saleability is also a concern. We've got bins here and there but all within 5-8 miles. I'd like the ability to add on more connections in the future.

 Does anyone have experience with this specific hardware or anything like it? Am open to suggestions.

 Thanks, Casey
