I have the 1820 which is essentially the same machine without the interchangeable feature. I like it for all the features, plenty of power, ease of use, accuracy and especially ergonomics and comfort in hand. I got mine after reading reviews that rated it above some much more expensive brands and models. That said, I realize that it lacks the bearings and durability for heavy, continuous use. As with most of my tool purchases, at the price, if it lasts me ten years, I can discard, buy another and still be money ahead.
