Viewing large PDF files/books in iPad

[siteplan]

Does anyone know any good apps for viewing large pdf files/books in iPad?

I'm a designer, my consultants and clients usually sends me drawings in PDF format that has a lot of vector lines. I use Bookman, iBooks and Stanza to view them but they take forever and lags and sometimes crashes when viewing those PDFs. The files are not even that big, they are just +/- 250k but consists of a lot of vector lines.

Any suggestions?

GoodReader handles larger PDF files fairly well.

Thanks alot for your help everyone. I went ahead and purchased GoodReader, I would say that this is the best utility app I ever purchased - it has everything and it handles my PDF drawings very nicely. Thanks guys. I appreciate that, this community is very helpful.
