Battery Grip
2008-08-31Very easy to install. I used a similar grip on my Canon A2 for years and found this was a "must have" when I got the Rebel digital.

Works as it should
2008-08-29The battery grip arrived promptly and has been working fine. It immediately gives the camera a more professional look, even if its
only a battery grip. My photography teacher recommended me buying the
canon BG E3 since he had tried a third party version that didnt work so
well.

If you take a lot of pix in one session, you'll need this.
2008-08-20If you are planing on taking a lot of shots, this is one accessory that you want to add to your camera.
It comes with two inserts, one holds 6 of AA batteries, and the other will hold two of the in-camera batteries.
The grip has good ergonomics and well constructed.

A geat buy!
2008-08-01The BG-E3 BATTERY GRIP is a great addition to my Canon XTI. The grip adds more space to hold the camera(for people with big hands) and adds some weight to the camera so it feels like your holding something. Plus I got it a low price and on time.

Yeah, you should just get it.
2008-07-31When I was considering my first DSLR purchase, I was guided by price to determine what I would get. I wasn't really aware of the size difference between the xxxD cameras and many others. I ordered my XTI, and have been loving it. Then I picked up a 40D. For me, size does matter. I'm just short of 6'2", and have long, "piano player" fingers. I still can't afford a pro-size camera, but this grip has made a significant difference in comfort and holding ability. The ability to use two batteries is a plus. Yeah, just get it.

Laptop Scaling
Intel's Core 2 Duo is easily the best mobile processor on the market today, boasting sky-high performance and low power consumption. But which CPU is for you: the super expensive T7600, the bargain-priced T5500, or something in between?
This article will first take a look at the various versions of Core 2 Duo that Intel has to offer. We will compare Core 2 Duo clocked at four speed grades: 2.33GHz, 2.16GHz, 2GHz, and 1.83GHz in a variety of benchmarks and let you know how to get your best bang for the buck.
Note: We will refer to a Core 2 Duo “T7000�multiple times in this article. We were unable to get a Merom sample with 2MB L2 cache, thus we lowered the clock speed of our 4MB L2 model to 1.83GHz to perform near that of the T5600 (1.83GHz, 2MB L2 cache), resulting in our unofficial “T7000�nomenclature.
The Core 2 Duo Processor
Intel has two lines of Core 2 Duo processors: notebook and desktop. Core 2 Duo for notebooks is codenamed Merom, while Core ...
