Having flown my Phantom 2 for just over 19 months I'm ready to move to the Pro 3. Looking for advice on where to buy in terms of follow up service by the vendor instead of having to ship back to DJI. Are there any vendors that check the birds before they ship them out? Are there any vendors who can do relatively fast turnarounds on adjustments and repairs and are authorized by DJI? I can buy from B&H and have the bird the following day with standard shipping but while they are easy to deal with they offer no after sale services. I see Amazon suggested in one thread because they do quick replacements and refunds. I just want a bird that's going to fly. Thanks for your thoughts and suggestions.
