But is it a good buy at Rs 20,999? To answer the question, we have identified some key competitors of the phone and here we have elaborated their features which would help you get the answer of the question posed above.
Vs LG G Pro Lite:
LG G Pro Lite was launched in India in October this year. It comes with a 5.5 inch display but has qHD resolution against full HD of Q3000. Also, it has a dual core processor. Memory wise it is way behind the Q3000 with its 8 GB internal storage, 32 GB micro SD card slot, and 1 GB RAM. It has also only 8 megapixel rear camera and a 1.3 megapixel front camera. 
This 9.48 thick handset has a smaller 3140 mAh battery too. However, it comes with dual SIM, WiFi, Bluetooth, GPS, and DLNA.

Vs HTC Desire 500:
It has a 4.3 inch display with 480×800 pixels resolution. But it has a quad core processor -the 1.2 GHz Snapdragon 200. Also it has 64 GB expandable storage slot against 32 GB of Xolo Q3000. However, the Desire 500 has only 1 GB RAM (Q3000 has 2 GB RAM) and only 4 GB of internal storage. 
The Desire 500 has a much smaller 1800 mAh battery which claims to provide only 12 hours of 3G talktime. It though has dual SIM connectivity and has normal Android features like WiFi, GPS, Bluetooth, micro USB, and DLNA. Besides, it has an 8 megapixel auto focus rear camera and a 1.6 megapixel front camera.

Vs Samsung Galaxy Mega 5.8:
Though it has a bigger display (5.8 inch) than that of Q3000 (5.7 inch), its display comes with only qHD resolution (Q3000 has full HD resolution). Also it comes with a dual core processor, an 8 megapixel rear camera, and a 1.9 megapixel front camera. This 9 mm thick phablet has also a much smaller 2600 mAh battery. 
Though it has only 8 GB of internal storage and 1.5 GB RAM, it outsmarts the Q3000 with its 64 GB micro SD card slot. It also comes with dual SIM, WiFi, GPS, Bluetooth, and added GLONASS support.

Vs Gionee Elife E6:
It matches the Xolo Q3000 in most aspects. First of all, the Elife E6 has 5 inch display with full HD resolution (which means it has better Pixel density than the Xolo phone). It has also Android 4.2 Jelly Bean operating system, 1.5 GHz quad core processor, and even 2 GB RAM. It has also a 13 megapixel rear camera and a 5 megapixel front camera as the Xolo Q3000. However it comes with a smaller 2000 mAh battery but since it has a smaller display (5 inch) than Xolo Q3000, we expect the Elife E6 to provide good battery life as Q3000.
The Gionee Elife E6 though has a single SIM slot, but comes with WiFi, Bluetooth, GPS, and Micro USB port.

Vs Lenovo P780:
Like Xolo Q3000, it has huge 4000 mAh battery that claims to provide 43 hours of 2G talktime. However, it trails Xolo Q3000 in every other aspect. 
To start with, it has 5 inch HD display, 1.2 GHz quad core processor, 1 GB RAM, 8 megapixel auto focus rear camera, 0.3 megapixel front camera, 4 GB RAM, and 32 GB expandable storage. But it has dual SIM, WiFi, Bluetooth, and GPS. It said to have three noise cancellation mics.
Conclusion:
All these handsets mentioned above are available for around the Rs 21,000 price mark as the Xolo Q3000. But the Q3000 has nice mix of features that make it better than all the other handsets mentioned above. But does it performs as its features suggest? We will try to review the phone as soon as possible to answer the question.
