I can't decide between Einstein and AB800. it's the $$ difference.
I mainly shoot portraits indoor.
If you are tempted to consider the AB800 due to the price difference, I would recommend that you consider Elinchrom D-Lites. This is a very good quality entry strobe that performs quite well. I've used them on a few occassions, and I was very pleased with their performance. They paired up with my 600RXs very well, so swapping lights & adjusting power was pretty mindless.
Obviously, the AB series of strobes has provided a reasonable lighting tool for a huge number of photographers. This is apparent from their overwhelming popularity. Although I do not own any AB strobes, I've used them on several occassions, and they can get the job done. But many strobe manufacturers (including PCB) have moved forward with newer technology that provides various performance benefits.
Unlike PCB, which only offers one level of digital strobe, Elinchrom provides three progressive levels. The entry level D-Lites are priced in a manner that competes with the Alien Bees, but is a newer design.
If the price difference is an issue and you have your heart set on Alien Bees, I would suggest purchasing them used. If you have not committed to a particular manufacturer yet, and you are not ready to plunk down $500 or more per strobe, I think you will find that the D-Lites have quite a bit to offer.
But given the choice between Einstein or AB800, I agree with the previous responders. There's no comparison between the two; Einstein is the clear choice.
