Excalibur lights?

http://www.bhphotovide​o.com …r_2_Light_SP_Sy​stems.html

I'm looking at several different options here and trying to decide. Does anyone here use these lights? They're the SP Systems Excalibur 6400 640 w/s lights. I have only seen one reccomendation and that was in the FAQ link up top. Most entry level studio lights talked about in this forum are the AB's and the D-lites.

So how does this kit compare?

Plus, why don't any of these manufactures make it easy to find the max sync speed for their lights?

I have a pair of used Excalibur 3200's, the strobes that are one level less powerful than the 6400's, and they work just fine. The Excaliburs are older designs from SP Studio Systems, so they don't get the buzz of newer monolights.

There's more information on the lights at the BKA web site.

Maximum flash sync speed typically depends on a camera and not on the lights attached to the camera. Strobes have varying duration, but you can't use a flash shutter speed faster than the camera's maximum sync speed unless the camera system has an electronic workaround such as Canon's high-speed sync settings.

I have owned in the past the sp6400 sp3200 and sp1600. Honestly it was a waste on money. They are decent lights for the cost but because they dont have a built in fan, rapid firing of strobes cause units to malfunction. I recently sold them and bought a set of AB800 and couldnt be happier. For my needs I want fast recycle times and the SP at full power took like 5 sec or so. Alien Bee 1sec at full. Also another factor is size. SP are heavy and takes up lots of space in my travel kit. They require the use of a heavy duty light stand. the Alien bee are under 3 pounds and and 1/3 the size.

I bought a set a few years ago and they've worked reliably for me and I've been able to get addon accessories easily at a reasonable price. Never needed any product support from the manufacturer and I'm not even sure how difficult it would be to contact them. AB does have a good reputation in this regard.

When I bought them I posted a review of sorts....

Except from what I've read, you can't shoot over 1/125 with the d-lite 4's before you start running into problems.

What about the White Lightnings? Anyone know if they have the magenta shift problems that the AB's do? Is it worth picking up XL1600's over AB800's?
