Dianne I'm never sure how much a shelf will hold- strangely enough the nicer redeye 66 and 201 or black 66 (didn't know the difference) managed to stay on those cheap walmart particle board shelves...one per shelf and one was on the bottom. lucked out there I think! but they stayed there for years- the 201(or black 66) and 99 were on a sturdier dvd cabinet my dad made. not liking the machines on there now- their bases are sticking out because they're long..may center just one and find another spot for the redeye...
so many decisions!
