The guys at Modelithics seem to do pretty well selling their models -- at work we have a copy of their "CLR" library, since it's a lot cheaper to buy a copy than try to measure everything ourselves (particularly when it's just, "well, this MIGHT be a useful part... but is it worth half-an-hour to model it?), and we've found the models to be of very good quality.
Unfortunately I suspect that they probably don't have models for the particular transistors Joerg is after. They're more than willing to do so on contract, of course, if there's some money around.
I suspect as electronics becomes further specialized, more and more manufacturers will just contract with a place like Modelithics to produce models rather than developing them in-house -- particularly any manufacturer that isn't doing "cutting edge" products.
One of the vendors (IRF) actually wrote back that when there is enough business in my case I might be able to convince a sales guy to get me a model. Oh well, another company has already been financially impacted by this old piece of American sales wisdom because I went to a competitor that had models: "If you don't take care of your customer, somebody else will".
I think it might have to do with product liability. The controls on discrete device manufacture are looser than with I/C's. Thus the reluctance to release models, particularly a collection of models necessary to represent process corners.
So Joerg may be shooting himself in the foot if he relies too heavily on the models provided by his "helpful" vendor.
