This maybe more helpful thread for Windows phones.
I used Lumia 540 temporarily for few days. Excellent phone. I will shift to Lumia once it officially launches some 4G models here, like Lumia 550.
In 15000, you can get lumia 540. No HD video recording or Gorilla Glass, but overall great speedy phone with solid build quality. Its clearblack display has great sunlight visibility and its 294 ppi IPS display is noticeably sharper than 294 ppi Amoled display. IPS displays are always sharper than Amoled displays, even if both are same ppi density.
However, I noticed that Microsoft Lumias usually get warm to hot while Internet use, but they don't have overheating issues.
