300mw + 300mw 650nm red 20x LOC

I guess for the $ the red DVD 20x LOC 650nm are the best plus a PBS cube for getting the hottest burning laser rated at 5 for an emitter size with mini glass lenses (thin beam) for a total of around 600mw+ that should do the trick even set to infinity...because the green lasers sure burn well set to infinity at 600mw right? For total cost would this be the cheapest and best burning route to go for maximum power in the VISIBLE range?

I would go with 2 BR's with a PBS cube to get lots of burning power.
