If cost is an issue, then try to find a used setup for sure. I agree that SE is probably a better choice for you because it spreads light better, but be careful about the ballast and bulb combination you choose because there are some very poor 250w SE combinations. Another thought would be to use 175w electronic ballasts with Iwasaki 15K SE bulbs, this combo is a "par breaker" and puts out more par than many 250w setups.

How would 2 Lumenmax 3 DE 250W fair? With Electronic ballast, say a galaxy 2x250W?

^ Excellent choice provided you take care to choose bulbs that would perform well on the 250w electronic ballast. The Gieseman 250w DE 13000 and 14,500 K have high output on an electronic ballast. It's a shame the dang bulbs are so expensive. Giesemann's DE perform much better than their SE.

Check Sanjay's lighting guides for other bulb choices. As far as electronic ballasts go they all perform very similar no matter if they are IceCap or Galaxy according to Sanjay's testing.
