Has anyone here tried any of the online print services? Places like: Persnickety prints, http://www.shutterfly.com/, http://www.cardstockprinting.com/, http://gotbigprint.com/.

Most will print on 80lb, 90lb, 100lb and even on 120lb stock. Got Big Print will also print directly on .030 styrene.

I also found a great cross reference on paper weights here: http://nycprinting123.wordpress.com/2009/08/04/lb-vs-gsm-vs-pt-paper-weight-comparison/
