Does Anyone know where to get a RPI touch screen From?

I have was able to find 7" and 10" touch screen displays.  I purchased the 10" and am very happy with it.  The set up was extremely easy and it worked right away, even before calibrating.  I have a model B rPi and decided to try and build a debian linux powered tablet.  I purchased a lithium ion battery to power everything and included a 4-port usb hub and an HDMI splitter so I can mirror my screen on a tv or projector for presentations.  The 10" screen works perfectly for my set up right now, although I'm still working on designs for a case to house all the components.  I've decided to print a case using a 3D printer rather than trying to cut one out of any other material.  I'd like to keep this as slim and lightweight as possible.  If anyone knows anything about 3D printing, I'd love some tips.

7" display - $124.99

10" display - $134.99

Both include:

Touch Screen

Assembled HDMI-LVDS converter (makes the screen a touch screen)

All necessary wires for connecting to the rPi

*MUST BUY RPI SEPARATE*

Once purchase, simply follow these instructions all the way through calibration and you're set to use your finger as a mouse. 

If you want a touch screen keyboard:

Type into terminal:

     <sudo apt-get install matchbox_keyboard>

Or follow these instructions

I have only 2 complaints:

1) I've had trouble using a usb connected mouse with 'ghost movements' causing the cursor to jump all over the screen.  Further research revealed a way to calibrate the sensitivity of the touch screen, but I also found out that whether or not the screen is properly embedded in some sort of a casing actually does make a difference. Instructions of how to calibrate and more information on the cause of the problem can be found here http://www.chalk-elec.com/?p=1702.

2) I've also had trouble with using my finger to click and double click.  It seems that every time I touch the screen, it instinctively thinks I'm trying to drag and move icons around on my desktop.  I'm wondering if that's also an issue with having a free standing screen.

If you need any help send an email, im ngdouventzidis@gmail.  I have never used this site before, just came across this thread and registered with the site so I could help.  Good luck

According to the instructions on the site for this panel with the raspberry pi,

http://www.chalk-elec.com/?p=1576

the panel and circuitry requires a 2 amp power supply, separate from the pi's power supply, so I suspect your run time must be pitifully short.  What battery are you using, what is your run-time, and what is the measured actual current draw of the panel and associated circuitry?

The HDMI LVDS board is what gets powered, then the pi is powered through that using a short usb cable that came with the screen.  That is a concern of mine though, but the usb hub is mainly going to be used for external desktop harddrives with their own power source and the occasional 2g flashdrive.  The HDMI doesn't supply power, and tvs and projectors have their own power supply.  The battery is just a cheap 20 dollar battery, i'll have to find a link if you'd like.  Im not a computer genius, in fact I'm majoring in environmental studies, i just wanted something to use for presentations and to take documents to and from class.  When I take the time to improve the design, the plan is to try and adapt a much more powerful battery, like a laptop battery, but that is off in the distant future.  At the moment, I don't have the battery connected, I need to purchase adapters to connect to the LVDS board.
