Help! Softbox w Grids

Help!

I'm doing a shoot in 2 weeks and would like to do a nice easy setup with 2 side lights and black background. Strips are ideal but I would like to use even just regular boxes as strips.

I currently have 2x AB's but also have flash strobes so I would like them to be interchangeable.

Any recommendations for cheap and fast?!

Check out FotoDiox and Cowboy Studio they have some cheap but good modifiers.

Cheaper and faster: flag your square boxes using a piece of black fabric. You can get them at Waldo-Mart for ~$10 or less.

Sheets of black foamcore come in handy too.

I ended up getting the Raya 24" softboxes and the Impact Grids which fit just fine! They work well, a bit of work to set them up (not much but it can take 1/2 hr to set up 2 softboxes for me anyway).
