A four shelf Vulcan rack is $99. The "extra shelf kit" is $49. Pretty fair price, actually. My home built flexi-rack cost about the same just for the parts. When we shopped for racks for the exhibit we found most "inexpensive" audio racks from Sanus and VTI and the like were a lot more. Plus they weren't the least bit interested in having their racks in our room.Why are 5 shelves $149 whilst 4 shelves is $99? Why are shelves $99 in the first place?
If you know of a lower priced system let me know. My focus in writing about audio is always on low cost, high value gear.
