It seems to me that the whole issue with microarrays is vastly over-rated 
(or misunderstood).

They can be as complicated as you wish. Microarrays, with 1000s of genes, 
allow you to do some pretty fancy studies. But you don't need to extract ALL 
possible information from a microarray experiment for it to be useful. It's 
just a big dot-blot, after all...

It's not difficult to design and obtain very useful information, with 
home-brew or otherwise arrays, using relatively uncomplicated tools. Just 
have a stroll by the BioConductor forum, for instance.

I have one good example of dealing with a company who "thought" they 
understood the experiment a colleague wanted to do, and proposed rather 
ludicrous controls. Fortunately we could stop that before it became 
expensive. Sure, companies may provide a useful service. We are in fact 
going to use Nimblegen for a particular experiment. But there's no 
substitute for doing your own analysis, at least to some extent. After all 
you are the one who knows exactly what the questions are...

Home-made arrays can be just as good as any commercial ones, providing you 
follow some common sense QC procedures. Why are you so dogmatic?
