I used J&L Party Rentals for supplies for my rehearsal dinner and wedding.  I went in just browsing around and pricing items out multiple times.  The staff was alwasy very friendly and gave me a chaces to look around without high pressue.  The owner gave me some ideas for decorating for my wedding reception.  They also suggested that if I found things I liked elsewhere, they'd be happy to purchase them and then rent them to me.  You just don't get that kind of service with other rental stores.
Pros:  Affordable, friendly, and professional
