A Good PDF Viewer

No doubt PDF Reader is better than any others I have tried. All of its features and the smooth look make it definitely a good purchase. However, I have noticed it lags considerably when viewing PDFs larger than a couple of pages. Sometimes with 3-5 seconds delay time, which may not seem like much, but when trying to scroll through pages, it gets pretty annoying. This only happens on documents larger than 3 pages, normally. That is the only downside I have found.
