Thanks for your question and interest. I am always thinking of lower priced products, have actually designed a few and then shelved them for various reasons. (Some folks have prototypes) As Empirical Labs grows it will become more likely that we will do some MI (under $1000) products.
Our motto has always been to "design a few good products and support the hell out of them". As a small company, you can only support so many products well, and therefore, we have kept our product line lean. We also like to be thought of as kind of a premium company (if I may be so pretentious) and by keeping everything "professional" - I.E. balanced (differential inputs in and out), with military grade parts, unusual features, easy to use controls, and of course good customer service etc, it helps justify our higher price.
One other basic business reason keeps us from making lower priced gear... If we made a cheaper compressor for instance, it would affect the sales of our premium stuff. This would give our guys more things to do for more products, therefore not only split our market, but possibly cut into the time we spend tweaking, QCing and supporting our more premium gear.
