i definitely looked at the d-lites but found some build issue reports with the units and also the trigger for the camera shoe (skyport issue in general). didn't notice a battery option either. i'd rather go with the bowens gemini myself, if in europe.
The units are manufactured in India to keep the price relatively low, but I have no issues with my set. The actual D-Lite RX looks better built than the previous IT model. The stands are also economical models, but they support the units well, and I can also use the with a Manfrotto boom without issues - just added a sandbag.
They come also with the newer Skyport Speed. The good of the Skyport is it's very small and light, the downside is it's run by a button cell, if it's almost depleted it could work erratically, better to keep a spare around because it's not a common type.
The system is also compatible with the USB controller that allows units to be configured from a Windows or OSX PC. There's no portable battery option if you need it, probably not to eat into the Quadra product.
Sure, you can get build a better kit buying separate items, but for a beginner this is a simple comprehensive and versatile solution.
