Based upon your use case, the MD 1000 with SRAM drive train would probably be the best option. Quiet Kat makes a nice trailer for hunting that you might consider. As t o whom to order from, I'd say Leili is selling more MD1000's and so might be the better option. I liked the way they handled the complicated battery recall situation although some owners might not agree. In any case, it's a great bang for buck purchase and a long delivery wait will be the case any way you choose to go.
BTW, if you want to ride more than 40 miles a third battery is advisable.
