I am thinking about investing in a vacuum press for my veneering and marquetry projects and could use some input. does anyone have a Compact 150 from Vacuum Pressing Systems or an Excel 1 from Veneer Supplies.com. Do you like them? Are they so noisy that you have to leave the shop while the glue dries? Also what is the difference between vinyl and Poly bags? I am thinking that I would not be pressing anything bigger that 48x48.
