I really wanted 4 lights and considered 2 BXRi's and 2 D-Lite 4's. I ended up going for the superior BXRi's, but only 3 due to my budget. No regrets.
Although I wish to take my photography and studio skills much further than where I'm at presently (beginner to the studio!), I currently practice in my home. I only have 8 foot ceilings and had the need to place the BXRi right up at that height. I'm 6ft and couldn't reach the buttons, so being able to simply push a button on the Skyport transmitter really did put a smile on my face I love it, haha!
I've put each strobe on a different group so simply switch the number on the transmitter and go up and down in power for each one, and being able to switch the modelling lamp on and off in the same way is great. Also, even if the strobe is down low and looking up to light a background, you have to kneel and get you head very low to see and push buttons.
I think you may regret going for the D-Lite's, especially if you ever get the chance to use the BXRi's
Thanks for the input. Ever had a problem where you could not turn the 500BRXI's down low enough?
