I'm looking to source some specific satellite equipment and would appreciate detailed information on your offerings. I'm particularly interested in satellite finders that assist with signal detection, a versatile satellite decoder that can handle multiple functions, and a 60cm satellite dish. Please provide me with product specifications, available models, and pricing options for these items. Additionally, I'd like to know about any bulk purchase discounts, lead times for delivery, and warranty conditions. If you could also share details on your after-sales support and returns policy, that would be great. I'm hoping to establish a long-term partnership, so your prompt response will be greatly valued. Looking forward to your reply!
