DIY air fuel meter from australia

Hey,
Im looking to put an led air fuel monitor in the unused square dash filler plate to the right and below the steering wheel. I found this company from australia that makes such a thing for a great price.
it looks like this after you solder it all together (no idea why they put their leds backwards in this pic).

(i will most likely use rectangular led's instead of round so i can compress them into the space i need to fit them into)
Link to the compay is:

Link to a place where you can get it at an even better price(small orders) is:

There is no print catalog available to the usa but they are available in NZ and AUS.
Anyone have any experience with this company? Im going to order this and try it out.
Looks like i will be doing several mods from them including the dome light delay, voltage indicator, air/fuel and possibly frequency switch.
Im sure some others of you will find this interesting. I have similar products in my vw's from a company called http://www.duostyling.com and im hoping to replicate the duostyling type gauges for my honda switch plugs.

There is one fairly close by. I'll go there tomorrow and get a catalogue.
I realize putting these kits together probably requires some time and a nice soldering iron but they make some excellent stuff for custom DIY electronics.
Of course I wouldn't try and tune a car with a L.E.D. based 14$ air/fuel indicator just like I wouldn't with an autometer air fuel gauge connected to a factory narrowband o2 sensor. I definately appreciate your heads up about that though its a good warning.
I like some kind of visual refrence telling me what my o2 sensor is doing, it comes from vw's where you have no idea if your sensor has gone bad. theres no check lights.
It works spot on and never had any problem with it.
