45 inch Nilus LeClerc jack loom for rug weaving?

I have been weaving on a Nilus LeCLerc 45 inch jack loom for about 2 years and have made mostly scarves, placemats and table runners. I would like to consider purchasing Tom Kniseley's new DVD set called "Weave a Good Rug." Since part of the DVD makes suggestions on which type of looms are best for rug weaving, I thought I would check in here before buying the DVD. Thanks for any help!
