Harmony remotes are truly not built to last for the long haul.
I started out with a budget model that I picked up at Sam's Club years ago, just to simplify things for the family.
I got hooked on the functionality of the remote, but changing batteries every couple of weeks got old. After a couple of years, the buttons started to fail and I upgraded to the 880 model, which has a rechargable battery.
The battery charging cradle Logitech used for my model was pretty bad. You had to charge the battery every night and getting the remote to actually charge on the cradle is more art than science.
As time goes by, the contact points on both the remote and cradle wear and accumulate junk that makes it even more of a challenge.
You can't beat the functionality of the Harmony remotes. The Harmony database has had every new component I've added over the years, and it is simple to both operate and program.
The price you pay is basically for the database of components. The actual physical quality of the remote, battery, and charging mechanism is far below the price you are asked to pay. Many of the remotes that come with components seem to be built as well, but are severely limited in functionality.
The only trick in picking a model is to make sure the one you get will handle the number of components in your system. After that, it's really just a question of whether you want to recharge, or change batteries. If you have a setup where your components don't have a line of site with the remote, you'll need one of the upper end models that handles sending codes thru walls.
