High intermod rejection and trunking don't go together unless you're using a commercial two-way radio. Many of the high-end receivers such as what ICOM makes are vast improvements over the Uniden and GRE/RadioShack scanners. The problem is they don't natively support trunking.
I would only suggest going the Motorola route once you understand many things: costs of the hardware and software, the difficulties of monitoring trunked systems, and learning how to properly program equipment. It's equipment you just don't go out and buy without any prior knowledge.
