I have a scar and I like it (airsoftmegastore.com). I opened mine up to fix the mag catch (which I broke by mistake) and the 2010 models have metal bushings instead of the nylon ones form before, so DBoys is trying to improve their guns. The hop up unit is still clear plastic, which I do not like and mine came with a broken inner barrel clip, but it still worked perfectly eventhough I just taped it together while I got a new one. I say go ahead because you cannot beat it for the price. There's also the SCAR from G&G which would be a high end gun and a lot more expensive. I have a G&G M4 and it is by far my favorite. Very accurate, very smooth, quiet and has lots of range. It might be worth the extra bucks.
Good luck.
