南非采购需求：挖坑机变速箱

I'm looking for a quote on a specific gearbox model for a post hole digger. It would be great if you could provide the pricing details along with the shipping costs to Johannesburg, South Africa. Please include any bulk purchase discounts if available, as I'd like to consider future orders as well. Additionally, if you have any recommendations or alternatives that are similar in functionality and quality, I'd love to hear about those options. Quick response would be appreciated since I'm eager to finalize my procurement decision soon. Thanks!
