I would like to find a used MyChron 3- 4 or one I can afford.

I would like to update my current data system without taking out a second mortgage on my house. I have  the standard Caterham dash light system and standard gauges. I haven't got the confidence that the gauges are not all that accurate.  They vibrate and crack and fall out of the dash. That sounds like I'm dissatisfied but I'm not, what can I expect with a 13 year old car. I've been told by a reliable source that is very common with Caterham. I would like to find a used Mychron or equivalent system or any model at a reasonable price. Can anyone help with this?
