You can probably get a 200 w/s power pack with a battery for less than $200. Or you can get a quantum X2 strobe. The benefit of the quantum is that you can adjust the light output on the head, so when you us both heads, the quantum gets it's power and the lumedyme head will get 200-X. Great for ratios, if you'd like.
Mr Chen, Experience comes with ripe years, as for me, I lack those years with light, however, with all of this excellent advice, I shall prevail!! Thank you all, for your time, and aid! Now, I am off to plan some actual photography, as soon as I feel inspired!
