Ignore all the unfavorable reviews of the Dazzle DM4100, unless you like AOL or would recommend AOL to a friend. I tend to be a tough critic when it comes to inferior technology, but the Dazzle TRULY IMPRESSED ME!!! 15 minutes to install on an AMD K6-450 notebook, default settings, smooth 30fps better-than-VHS capture, and a reasonable price. Yes, the video out works well too, naysayers! OK, I had to figure out a couple of software issues as I experimented with options, but if you can't deal with software quirks, you shouldn't own a PC !! ....but if you do, you probably think "AOL is #1" means AOL is the best. No, it just means an unrelenting high-budget sales campaign can easily brainwash the cranially-challenged. The rest of us just ignore the ads, and enjoy using quality products like the Dazzle 4100, without opening the manual, or whining to/about tech support.
Finally, you'll want to pay attention to sharing capabilities. In the past, you only needed to worry about saving your videos to a DVD or a highly compressed video file, but the rise of Vimeo and YouTube has resulted in new sharing options. If you're looking to share your videos to your social network, make sure that your software is capable of doing so.
The T#i line is what they call a "pro-sumer" line, which is basically between a consumer line camera like a very basic DSLR and a professional DSLR camera, thus the term "pro-sumer." Typically what this meant is an DSLR with an APS-C sized sensor, decent resolution, and some hand-me-down professional features of pro-grade cameras from a few years ago. For this reason, sometimes it's not worth upgrading from one of these cameras to the next until at least a few generations have past (meaning if you have a T5i, it's not really a giant leap forward to upgrade to a T6i). However, the T7i is somewhat different. When I was doing research on what features it has and what it is missing compared to the pro-grade DSLRs that are considered "current" right now, I was surprised to find very little. The main differences really is that the pro-grade cameras have the LCD display on the top that would display all of your relevant camera settings, and then a few of them would also sport a full-frame sensor. Other than that, the differences are very minor. Something like maybe 1 or 2 frames less in burst mode or something like that. Nothing that would really jump out at you and make you regret not stepping up to the professional grade equivalent (Think it would be the 77D?). It actually has pretty much all of the big features of even their current pro-grade DSLRs, making the T7i probably one of the best prosumer DSLRs to buy.
