I'd like to see more designs in wood.
I have a Bell'O black and glass rack, but would have preferrred wood to match my furniture. There's nothing wrong with the "open" metal and/or glass styles out there (except for maybe more flexibility in adjusting shelf positions), but having been through an extensive search recently, I just couldn't find what I wanted in wood. Unfortunately, what was out there was either very high-priced or only available in Cherry and Oak.
I kept thinking that if a good sized woodshop had the jigs made, is it any more difficult to put in stock of Beech, Walnut, or Maple?
