I was also about to say modcrate. Less than $5, you've got to to crazy not to buy a bunch of screens. I bought 5 for myself. Never can have too many.

May be slightly off topic, this is how I extended my usb. You might think I'm crazy but it works great. Hooked up to escribe and it allowed me to upload a custom screen for "check atomizer." I used the pins of a micro usb plug that I tore apart.

And to stay on topic, you can see in the pic how I used heat shrink for the ribbon joint on the screen. I cut up two small pieces of an old gift card and sandwiched the joint. Then I surrounded the joint with heat shrink. Protection with a nice clean look.

I just used the micro usb port from the shark flask. I know that it will fit the shark flask so I'm going to stick with it. I had to trim it down a bit to fit the dna200. It works and still connects to escribe

I wish. The vs vf charging board is about two inches long and the dna200 won't fit. Two boards actually. I just cut it to size to just use the socket and extend the dna200s micro usb. The board fits in the slots perfectly and won't wiggle wobble which is why I salvaged it.

I always wished they would make a flask with a 200 in it......no room at all to work with and still keep the same form factor though....keep us posted. ...anxious to see how ur setup turns out

Also there is a link to a youtube video showing side by side comparison to this station and a real Hakko, the guy opens the box and shows the insides of both of them. I was quite surprised just how heavy the unit is and it looks like they made a couple improvements since that video. The temperature control is very accurate, I checked it against my Fluke meter with a Fluke thermocouple, I didn't have to adjust mine but there is an adjustment for the temp if needed. For the price, it's a pretty good station and works very well, I soldered some 12 ga wires to a 200 board and the 510 a couple days ago and had no problems getting a very impressive solder joint, key was a larger tip that wouldn't cool as soon as it touched the joint, and good no clean flux.

I broke down and bought a avg priced solder station http://www.tequipment.net/Hakko/FX888D-23BY-Kit3/Soldering-Equipment/ also got some kester lead solder paste and some flux pens going to try to do a better job on the connectors this weekend, I figure if I can solder the connectors with a crappy iron I should be able to do a professional job with my new iron (I hope :-) )

So if I understand this correctly you were able to solder a screen to a .05mm pitch cable and extend the display on a DNA200 but by soldering directly to the contacts you need to have a reverse or opposite side contact cable to make it work with the zif connector on the board.  Can you confirm this assumption on my part.

I believe I found a correct cable on digikey http://www.digikey.com/product-search/en?KeyWords=150200084 to accomplish this for $5.83ea w/ about $4.00 shipping.

While I have no idea of the quality but these are available on ebay much more economically: http://www.ebay.com/itm/25pcs-Reverse-Direction-8-Pin-0-5mm-Pitch-FPC-Flexible-Ribbon-Cable-Wire-0-66ft-/161775574752?hash=item25aa935ee0 .  I've asked the seller for more information and pics of the cable ends but have not heard back yet.

Do you have any more input for those of us looking to follow in your footsteps?  What cable did you use (link) and what was your procedure for soldering that joint? Did you just flux the hell out of it and drag your iron down the ribbon contacts to tin them on both the extension and the display then line them up & heat up the display side using a wide tipped iron & a lot of pressure just like you were soldering a new display to the older small screen dna40?
