Best selling pico-projector update (July 2012)

Best selling pico-projector update (July 2012):
Here's our monthly best-selling pico-projectors list for the beginning of June 2012. We're using data from Amazon.com, which seems to be selling the most wide range of pico projectors. This list does not include embedded modules in mobile phones or cameras. Here we list the top ten projectors, with the price and position in Amazon's best-selling electronics product (which gives a better idea of the actual selling volume):

1. Optoma PK320 ($392, #1,047)
2. Optoma PK201 ($246, #1,467)
3. Aaxa P1 Jr ($99, #1,751)
4. Optoma PK-101 ($113, #2,028)
5. Optoma PK301 ($318, #2,349)
6. Microvision ShowWX+ HDMI ($369, #2,532)
7. Optoma PK120 ($198, #2,687) 
8. Aaxa P3 ($252, #2,790) 
9. iPhone 4 DLP pico projector ($249, #3,042)
10. Aaxa P4 ($296, #3,312)

The list is quite similar to the list from last month, dominated by Optoma and Aaxa.
