Choosing new drivers/crossover in a speaker build

This may not be the place for this thread, but I will take a chance. I am building a new set of speakers. Usually, I go with a full range driver and cabinet to match. This time around, I actually was paid in a pair of Scan Speak 8" drivers for my cabinet work. They cost $450 ea. or about that. I put them in a back loaded horn cabinet and couldn't be more impressed so far. Of course, these drivers are designed to work in multiway speaker design, and so I will be doing my best to find a good tweeter and crossover. I did see at Madisound, a 2 way crossover for about $600/pr. and so that likely will be the way I go for the crossover, or possibly build my own. Now, the usual tweeter used with this driver is also a Scan Speak, with a beryllium cone. At about $500 ea. I can't cut it. I will continue a search for a tweeter that can be crossed over at about 2khz.  

 Any ideas/experience with this?
