As Peter suggest, I would suggest you buy only one light right now; Einstein or AB1600. Why do people immediately believe 2 or more is better? This is especially true if portability is important to you. You can do a lot with 1 mono, a reflector, and the hot shoe flashes you already have.
~ If the 1 mono is your main you can easily use the hot shoe flashes for rim lights or fill.
~ If the 1 mono is your main the sun can be used as rim light.
~ If the 1 mono is your fill to the sun you don't need much else, or add rim with your hot shoe flashes.
These are only a few examples AND the benefit is your still keeping things portable by not having the other mono to deal with.
As for Adorama's FlashPoint lights, I had one several years ago. It was well built and very nice. However, they are not as small as the AB/Einstein offerings of similar power. In other words, the FlashPoints are larger...and this is the only reason I sold them and went with an AB1600.
I also went with PW ControlTL system because it controls my (Canon) hot shoe flashes and my AB1600.
