Lihn, I understand you have a tight budget and want to pick the right uke for you, but this is the third thread you've started asking essentially the same question. As you've probably noticed by now, you are unlikely to get a consensus here; some will recommend Islanders, others Kala and others yet Makala...on it goes.
You've made a good decision in buying from one of the uke sellers who will provide a proper setup. Now you must pick a uke. None of us can do that for you. No offense intended, but I think you are over thinking this process. Been there, done that. To paraphrase Nike, just decide.
