look here they have a 2 combos with the superflash: one with 1W headlight, one with 0.5W headlight. I'd spring +$10 for the 1W if I were doing that

PBSF is a very tried and true rear light, I have that one myself. I've read great things about the Mars 4.0 though and I think it may be even better and it's $5 cheaper.
Princeton tec eos frontlight + Mars 4.0 is the same cost as the top end PB combo. I compared the Princeton to the PB headlights at REI and preferred the Princeton, plus it has the accessories like I said
