Commission only income

I think I need to go back and reread some of Mark’s info on variable income but I wanted to pose this question to all of you. My job is commission only in an industry where sales are up and down without a lot of continuity. That said, spring is usually the busiest season so I hope to have a windfall soon.

I am currently on baby step 2 with about $12,000 of debt remaining to pay off. Would it be a horrible idea to put my debt payoff on the slow track and put a few months of expenses in savings first? I haven’t been working the system long and to be honest it scares me to death to not have a cushion in case I don’t have a check coming in a couple of months, which does happen. The $1000 emergency fund (guaranteed loans) won’t go far if I don’t have any money coming in at all.

Any of you experience the same sort of income fluctuation and how do you deal with that?
