You'll probably want to get into strobes, so consider them soon - even if you're not quite ready for them yet. Don't invest
too much in traditional camera-mount flash units if you're going to go this way. In the end, strobes can often be a better value - assuming you can use them.
I got the Einsteins from Paul C. Buff. They're a good value for the technology and quality they deliver - especially compared to most (perhaps all) of the competition. I even got their excellent Vagabond (mini Lithium version, in my case) and have ended up using it to power many other items besides the Einsteins.
Some of the great things about the Einsteins includes the color consistency, flash speed, recharge speed, ability to change settings via remote control (in case they're out of reach), and the fact that they have a socket for an inexpensive CyberSync (or a more expensive PocketWizard) transceiver. If you use the CyberSync (I do) it brings the cost to within $100 of the Alien Bees units with a CyberSync, yet it's more advanced and capable.

Of course, considering your location, I'm not sure how worthwhile it is (or isn't) for you to use a freight forwarder. But at least you should look at their site to get some ideas, and to get an idea of how much more powerful a mono-light strobe is than a traditional flash.
