Repligo Pocket PC PDF viewer

I have been using Acrobat reader and Words to read ebook on my Ipaq 1940. I Found Acrobat reader has

flawn in reflowing document. Unproper tagging pdf file can not be reflowed. It is readable, but you should press 'left' 'right' button to read every single line!

I found information about document viewer called Repligo from Cerience.
The application use 510KB. The price is $29.95 USD.
Anybody has comment about this Repligo?
