Ok,I bought it and I ran a couple of tests and from a very personal point of vue, I do like it a lot!
I love it's soft lightning and shadows, the way it renders, something I paid a lot for during my photographic days. You'll find the light shader HERE at DAZ.

Here are three test renders with different settings:

Rendersize 600*600
Full (sic!) 3Delight render
Bucketsize 8
Max RayTraceDepth 2
Pixel Samples X/Y 5
Shadowsamples 8

AreaLight settings:
Shadows ON
Intensity (+scale) 100
Area Samples 16
Falloff ON

Rendertime: 4 min 59 secs

same settings but
Area samples 32

Rendertime: 5 min 41 secs

Same settings but
Area samples 128

Rendertime: 10 mins 13 secs

My systems specs:

XP Media Center, SP 3, DirectX 9.0c

DualCore AMD Athlon 64x2 4200+ (2200MHz)

NVIDIA GeForce 7300GS (512 mb)
NVIDIA GeForce 8400GS (512mb)

still only 1 gig of PC3200 DDR SDRAM

double screen display.

So in my opinion, this is one of the best lightshaders you can find, specially when you are looking for a very soft lightning.

And just by the way:

What you see here is the DL UberPointSphere applied to the AreaLight, works with the fall off settings.

Damn you, I was so not going to get this!!  LOL  It's cutting into my M4 money and it's not cheap but boy those test renders are really nice and using our dear Wolfie too.  Hmmmmm........ Sigh.......
