What are some characteristics of a company that is a good LBO candidate?

Notwithstanding the recent LBO boom where nearly all companies were considered to be possible LBO candidates, characteristics of a good LBO target include steady cash flows, limited business risk, limited need for ongoing investment (e.g. capital expenditures or working capital), strong management, opportunity for cost reductions and a high asset base (to use as debt collateral).  The most important trait is steady cash flows, as the company must have the ability to generate the cash flow required to support relatively high interest expense.
