I bought the Jungle Jim racks last year at the Louisville Expo, and love them. The thing I like most about the new Jungle Jim trimmer racks is the lock down bar is held down tight by heavy duty springs. I bought the entire package (trimmer rack, blower rack, and a water cooler rack) for around $135. Think that was $65 or $70 off though.
If you're going to buy some the best time is always at conventions. That goes for just about any kind of equipment.
