you will only need 18250 if u want to travel light if not no point having 18250... ms color selling around 799.... 75-300 (normal) is quite good too... maybe u can consider having a tripod to help u when shooting long range.....
Herc85, thanks for the valuable advise. Yes, 18-250 is an excellent choice except it is rather expensive for me at the moment. Can you advise why is 75-300 good? So far, nobody has told me that 75-300 is good. And yes, tripod seems to be a mandatory tool for long range for me since my hands are kind of shaky.
