DEPENDS on "how" and "where" you'll primarily use it, and whether you have other cams better suited for particular applications.
From an "overall" perspective, the best value for around $300 is going to be "homebrew". The only significant downside to homebrews is they're not available in truly invisible "black" flash. But then, most of the choices on the commercial market aren't either, as most are "red glow" infrared, which I've found to spook game as much or more as white flash.
Unless you're going to true "black" flash, I'd look no farther.
If you have applications where "black" flash would be advantageous, CONSIDER the Uway NT50B. But be forewarned, the quality control right out of the box can be lacking. That said, I have found their return customer service to be between one and two weeks on the two items I've returned for not working properly. Not to "go off" on Uway, after all I am recommending them, but MOST of the trail cams made in China suffer from very poor quality control ---- many simply don't work, and you have to return for warranty repair (P&S at your expense, $12 + postage with Uway). Worse, it sometimes takes several weeks to figure out the problem is with the cam, while you've gone several weeks spending much time in the field with a cam that wasn't working. (Have to rule out battery and card problems first.)
The only other true "black" flash I'd look at is the Reconyx. That will be stretching your price range, but it should perform better than any the other "black" flash models. And you won't have to worry about spending weeks wasting your time in the field with a cam that doesn't work "right out of the box".
If you're considering "red glow" infrared, also take a look at the Leaf River. I've been very pleased with the performance, long battery life, and "ease" of field servicing. These can also be easily converted to true "black" flash by purchasing the Uway "Black" Flash Extender, and attaching it to the Leaf River.
Regarding the "black" flash, many users are going to be very disappointed in it's relatively short flash range. And because of its low-intensity flash, these cams are set with a longer exposure rate, resulting in a lot more poor blurry images at night. The flash range is greatly extended with the Uway "Black" Flash Extender.
I'm not so sure that the best way to utilize black flash isn't by using a black flash extender with a white flash cam. The white flash is disabled (either turned off or covered with black tape). Going this route, you should eliminate much of the blurry nighttime image problems of black flash cams.
