阿根廷采购需求：橡胶履带式液压挖掘机、橡胶履带式液压挖掘机、挖掘机铲斗、挖掘机加长臂、挖掘机加长臂、挖掘机快速连接器

I'm looking to invest in a mini excavator weighing between 1200–1800 kg, specifically one that supports an auxiliary hydraulic line for attachments. I'd greatly appreciate your best price for a unit and recommendations on which model would best suit our needs. Additionally, please provide prices and availability for augers with various bits, different bucket sizes, and hydraulic breakers. I'd also like info on spare parts distribution in Argentina, common spare parts required, standard components used, warranty conditions, technical support availability, delivery terms (FOB or CIF Buenos Aires), payment options, and shipping dimensions.
