I never ever sacrafice picture or sound for ease of operation (i understand primarily only picture). If a Pronto adds too much to the budget then the Pronto will make a great holiday gift.
Or use the macro capabilities of the integra remote and charge a fee for the programming.
We use Prontos with every system. The client can come home after a long day at work and enjoy their "entertainment system" and our referral rate is high. It's in both the client and the installers best interest.
Hope this is helpful,
