I have had dealings with these guys, good service, good product, very price competative. Although I have not had a gen set off them my mate has with exellent results, not a lot of work but ready when he needs it. Me I have a water pump diesel, 6HP electric start sitting down the dam for pumping up water to stock tank for the past 6 years. have to charge the battery up now and again due to non use but every time I pull start cord away she goes. Blew out the pump water housing due to frost the first year, they put another on the plane same day for $30. Spares and after service great.
