Nah, I'll tell you to sell whatever you can that keeps you profitable.
Sadly, few dealers I know have a very good grip on what their true costs are. They tend to add up product costs and add some overhead WAG and think they know what they are doing.

We have a lot of happy, profitable dealers who are quietly doing lots of $10k-$100k jobs and doing quite well at it. True, they have to do more jobs then they used to, (non-existent video margins have seen to that) but the point is they are able to physically do more jobs, and they are making more money in the process.
Like anything else, if you don't know what you are doing (networking is new to some A/V guys) then there is a learning curve. And learning curves can be painful. But it really isn't that steep of a curve. And you will have to learn it sooner or later...
As more and more of our entertainment is not based on physical media, even the doubters will eventually see why DigiLinX is such a compelling solution.

If you are making money the old way and you like CD changers, tons of cable etc... stick with analog and matrix switchers. If you have moved into servers, and your media is already networkable, then analog is a step backwards (in cost, functionality and fidelity). Take a long view of where our industry is headed, look carefully at where the sources, the future of entertainment are heading, and you will look more carefully at networking entertainment systems.
