if it's just an accounting thing than you can probably get away with quickbooks... but coming from Lucero that's a huge drop in features.
i haven't really looked into BrokerOfficeHQ,
http://www.brokerofficehq.com/ , but maybe that is something to check out. i only know about it from researching settlementroom which is a related product.
personally i'd like to see brokers get together as a group and create their own software product and not rely on outside vendors who tend to increase pricing and lock you into their systems.
