Hi tvp,
Welcome to the forum.
I don't give advice on to when or if one should purchase a product. I can only provide information so that you can make a more informed decision.
First Bradley does have a current promotion; 15% off anything ordered from them online. I've had the P10 for almost 2 years, and have not had any mechanical problems; except for a jammed bisquette, and I can add that removing the screws from the turntable to do repairs and maintenance is difficult.
Since I've had mine, Bradley has made some upgrades in software, and to the electronics. So I may be comparing apples to oranges. Bradley has great customer service, but my complaint with them is when there seems to be a "wide spread" problem they won't share that information with their customers, and will work internally to resolve the problem. And this leads to a lot of frustration with the customer base. So there may have been a batch of P10's that were manufactured with bad sensors.
Keep in mind that many new members come to this forum because they experience a problem; less so than those that are pleased with their product. Is there a problem "Yes"!! How wide spread is it, I don't know. I can tell you that when the P10 is running properly, it works well. If something goes bad, Bradley Customer service with work with you to fix the problem. Though paying that much for a smoker, it can be very frustrating when it is not working right.
