Hmm.. therein may lie the reason why the MX-6000 is not selling as much as the Prontos.

There are many, many potential customers who would like to do their own programming, and using complete system files that's available online (courtesy of MX-6000 users) and tweak them for their own needs.

Many potential customers may be turned away from the MX-6000 and go for other makes instead when they found how little system files are available. To those who may not give it much thought, the first impression they'll get is that the MX-6000 is not 'popular' amongst users, and thus can't be good.

URC might not have thought about this aspect when they did what they did (not provide the programming software out of the box like the Prontos), and thus probably lost a significant amount of sales there. Oh well.. *shrugs shoulders*
