cricket vision is slower than the old board but more reliable. Smart parts have changed the manufacturers for their electronics after there were so many problems with the older ones.
There are no real advantages to getting a cricket if you dont have a vision board, its only worth it if you have a vision eye. The only thing it is good for is reliability, as these boards are bomb proof now the initial flaws have been ironed out.
With the new cricket vision it automatically adjusts to paint colour, is easier to operate and has a puch button dwell, which is hella easy to use!
spend the 100 quid on a lpr kit to reduce your operating pressure, making the bolt pinch paint instead of chop, i can think of many ways of spending 100 quid to make the performance of your impy better than a new circuit board.
hope that helps
