Propane powered mowers...Good or bad for the industry?

[mrlpg]

Recently, propane mowers have been getting a lot of attention as a viable option in the lawn-care industry. Local conversions and OEM mowers are showing up more and more often. There are plenty of incentives for the end user to make this an attractive option, most notably tax credits (.50 per gallon), rebates (in several states) and lower cost of fuel to name a few. As a non lawncare businessman that can help your industry drive down costs, I would like to gauge an interest level from the professionals here. Have you used them, or converted a mower? Have you had any performance issues if you are using one? How easy was it to convert? What would be a concern of yours? Good, bad and all solid opinions welcome. Thank you.
