What has worried me is that the abts system is taking the place of like 10 of the less advanced systems. In this case a firm buys one or two from aehr and doesn't need anymore and therefore you don't have the multiple number of sales like i have seen in the past. Recently i seen one order i think from 2009 of $15million. Now, i'm seeing the same production capacity in one or two systems. Prices aren't going up so you have high reseach and development costs and a lack of sales. It doesn't look good.
