I have no problem with Falcon Northwest. I have known some Falcon Northwest owners and they have all been happy with the product. My biggest issue with Falcon is that they don't offer much of a selection of notebooks.
I don't care for Voodoo PC, for a couple of reasons. I don't get the feeling from their website that they take quality control and customer service very seriously. I haven't dealt with them myself, but some of the stories there are pretty bad. I think that given that, there is no way to justify the inflated pricing. I also don't care for ElP, who, as I mentioned earlier, has been caught in at least one lie about one of his products. Also, ElP has a tendency to knock his competitors. I hate that. Sell your product on its own merits. I believe that the only reason sales people knock other peoples products is that they know those products are better than their own.
One thing I will say about this type of operation, be it Falcon, Voodoo, Hypersonic, Savrow, etc. I think its ridiculous to complain that it takes a while to get a computer from them. The system is being custom built to your needs, and that takes time. While I think it would be nice if they would keep some kind of inventory around, they all seem to think that there isn't a business case for this.
