I purchased my INK-DEK 4/68 from
www.dekdevelopment.net last year and love it. It's on a lazy susan and each side holds the matching marker, pad, refill, cartridge and cartridge refill. Now that SU had discoutinued a seperate refill for the ink cartridges, I use the open spot for my jumbo cartridges. The space where the pad goes is tall enough to fit both the classic and craft pad, so you could use the extra slot for the craft refill.
In addition, it had a "well" on the top where I store all my wheel handles. My punches are also stored on the top. On the bottom, there's room for my watercolor pencils and my pastels plus spaces that right now house my 6 Staz-On pads, 6 spectrum pads, my VM pad with refill and versamerker AND I still have a section that empty. There are also 2 big drawers to store stuff. To give you an idea of the size of the drawers, in one I have 4 jumbo wheels and 17 regular wheels (although, I just purchased a rack and as soon as I stain and varnish it the wheels will have a new home).
I looked into a lot of different options before purchasing this unit. It costs more than most that are out there, but it holds so much stuff that I thought it was worth the price. I don't regret my decision at all.
One thing that may be a disadvantage to some is it's size. It is a big unit. I happen to have a perfect place for it (a corner spot on my L-shaped stampin table). You can find the dimensions for it on the website.
Happy shopping. Whichever unit you order, it'll be like Christmas when the box arrives.
I couldn't wait to open mine and fill it with "stuff"!
