As I write this, there are a couple of other threads on the first page of this and/or the Pronto NG forum about starting out. The basic answer is that the software is free, all sorts of images and IR codes are available for free here, but it will take you quite some time to do the finished remote.

It might not take you too long to get each individual device into the remote, but then you will have to go clumsily from one device to another to do what you want -- just as you have to pick up three remotes, usually, to turn on any particular video source.

If you want to learn this stuff, go for it. If you are looking for a finished product, let us know whereabouts you live, and maybe someone on the forum can do the work for you. It comes down to your own preferences as to time to learn and how long it will be before you can bench the multiple remotes that work your system now.

One guy said it can take 1000 hours to program your Pronto. He programs them, and meant HIS OWN Pronto. I suppose so. With client remotes, I used to spend time over and over on customer ccfs, being sure every item on every page was spaced perfectly, and lined up with every other similar page. Now that I have done that, I can use the same panels or easily recreate the same idea. You can't yet because of lack of experience. Also, when it occurs to you to add something (to your own), you are likely to drag out the computer and do it. The time can add up.
