Ok, I have finally decided to get some lights. As this is strictly a...er, a hobby (i.e. I earn a living doing something unrelated to LF photography), I'd like to not spend a fortune. I;m shooting small groups of people with 4x5. I use mainly 320TXP and HP5+.

I was looking into Speedotron packs and heads but, I think I need something more portable.

So, this brings me to point...

Will a couple of Alien Bee 1600's be enough? What f/ stop can I get?

Same question for the White Lightning 3200's

I would really like to get a couple of Speedotron Force 10 monolihts but the cost is prohibitive. Can I get by with one? even one would be well beyond my means right now. ...I have maybe $800 to spend - if I sell another lens....
