Hello not a lot of responses - so I guess I"ll tell my story. After a long journey I have settled on the AAXA P2 projector. I managed to get it for $315 with coupon so it ended up being the best fit for me!
I ordered the Optoma PK101 first for $230. BIG mistake. The projector arrived, nice packaging, very small and light, ran very quiet, but the brightness was terrible and since it had no video player I couldn't even view my black berry storms video as I found out my cell phone had no video output. Also the resolution is very low - only 480x320. I ended up returning it.
The AAXA p2 on the other hand is about 2x larger, runs very loud but it has higher resolution 800x600 and 33 lumens which is just about bright enough for me and a great relief after trying to use the Optoma PK101. The extra brightness and resolution is very good since I am connecting to my laptop mostly. If anyone is interested I'll post up some pictures later.
Here's a link to the AAXA website - keep in mind the battery pack is pretty big so it's a lot thicker than the Optoma projector.
You can find the AAXA projector here. The coupon code I found on fatwallet, it saves you $40 is P1owner43981. I have no idea if it still works.
There's also some deals on the 3M Mpro now for $150, but I hear that it is really less than 10 lumens so it probably is not bright enough for most people.
