Try it, then buy it!
I tried probably 7 or 8 different apps before I found twitbird. Many of them either had intrusive advertising or just plain werent very good. I tried the free version of Twidbird so good that even though it did everything I needed, I still wanted to pay for the premium version. Its had a few hiccups along the way, like sometimes it downloads the same messages twice, but by far is the most feature rich and at the same time easy to use twitter client that I could find. Love it!
