Never owned one, but it is on my list. I handled one at Bass Pro, and it seemed solid enough. The build quality and fit/finish were more than acceptable, especially for the price. The only reason I didn't buy it was that I wasn't in my home state at the time.
The main reason I want one is the completely ambidextrous controls - my wife is a lefty. She is also more comfortable with a gun that has a lot of safety features, and the 809 certainly fits that bill.
There have been a few different iterations of that particular firearm, and the current one seems to get good reviews. It also has a nice look to it. I especially like the gray framed one that Bud's is offering for just under $300.
I have one Taurus - a PT111 G2, and it has been nothing but reliable for me. In fact, it is my EDC. I am, by no means, a fanboy, but if the quality of my current Taurus is any indication, I say give it a chance. The lifetime warranty also sweetens the deal.
