Wow, thank you for the "Pep talk"! I needed this!
I am a very satisfied DS owner, for about 8 years, and have never regretted that purchase. I can also say that it was my first, and so far 'only' DSLR. I use it frequently, but not a lot by any means. I have received very good comments and opinions about the pictures I've made with this little old camera that could.
Of course, I would "like" to have a newer, higher spec'd camera, and came really close to getting one for a gift this Christmas. Only my wife deciding that we needed new furniture, and a bigger TV, kept me from doing so! I had to sit on my "wants" and go with "needs" this year. I am considering getting another lens for my DS, and will probably do that, since one of the best things about Pentax is that I'll be able to use whatever lens I get now, on a newer camera later!
Even after 8 years or so, I haven't fully utilized and learned all the abilities of my old camera, and thanks to this forum, and the answers I've gotten to some of my dumb questions, my enthusiasm is renewed! I also joined a small, local photography club, and while my little DS gets some raised eyebrows and long, down-the-nose looks, it can do most of what their "better" cameras can do. Plus, it is always nice when every now and then, I win a very small in-club photo competition with my dinosaur!
I've wanted a new one, but through fate, luck, divine intervention, or whatever...I decided to use what I've got instead. I like and am very familiar and comfortable with my DS - kind of like a favorite pair of old jeans or sneakers or T-shirt! It just feels good.
