What model/brand of active crossover is anyone using? There doesn't seem to be too many options, and they all are really expensive. I'm not sure I want to spend $1,000.00 on a crossover. I have a DBX Driverack PA2 and a couple of old 2 and 3-way DBX crossovers.

My other options would be to run one passive crossover, use a 3 and 2-way in series, or run two 4-ways in mono.
