I bought a cheap ($500) set of 4 Britek lights from an ebay shop when I first got started and they served me very well for over a year and a half. I know that's not long when comparing them to the longevity of higher end professional lights, but they served me well for what I paid for them.
I recently upgraded to 4 DynaLites, and while I expect them to last many years, I paid out the rear for them.
A year may be just the right amount of time to learn a little about strobe lighting in the traditional way (3 or 4 light setups), and give you time to save for a nicer set.
Here is an ebay auction selling 2 Briteks. The set I got way back when had these two heads, a backlight and a boom with strobe, a couple umbrellas, a couple light stands, etc. ebay auction
P.S. I am not endorsing this ebay auction in any way, just pointing out the type of strobes I started out with.
