Wait until they have the "professional" stuff on sale. Like most of the power tools today, I think they are pretty much just mediocre.
They work as well as my PC, DeBlack and DeckerWalt, etc. on the job. Like the Black and Decker/DeWalt relationship, there are some noticeable differences. The regular drills have no name batteries; the pro has Panasonic. The regular drills have nylon/plastic and aluminum drive trains; the pro has all metal.
One thing they have though, is a great warranty program. You can buy a tool and use the crap out of it and if you bought the extended warranty they will replace it in the store for up to two years if you kill it. Notice I said replace, not repair. No waiting, no fighting with some technician, no down time requiring you to buy a tool to work on the day's job.
Many of the other tools that have these long warranties require it to be sent to their service center, then it is evaluated, then they will tell you how they will handle the warranty, or if they even will. This can take a couple of weeks, then another week in the shop.
So if you like the tool, buy it if the price is right.
