Insight please

Im about to start a 4x8 flood and drain table only thing im missing is lighting. I wanted to go led but cant afford to light it with the price i was quoted. Now im looking at the CMH lights. Would you guys get those over the hps? Also how many 315s or 630 watt over the 4x8?

4 x 315s with adjustable batwing reflectors ftw.
Or you could go for 3 cmhs and some diy led strips to mix in.
