I'm the researcher in the family. When we considered a floor plan with a kitchen that only fit along two walls, I scoured the internet for movable Islands. Wanted movable, because when slides pull in, you lose some of the width depending on the set-up. So we wanted something we could push towards the back of the unit where there was more space.
I'm also a big fan of HGTV remodel shows and they've taken standard wall cabinets (because they are narrower) and turned them into Islands. Just add a lightweight wood look countertop, maybe some wheels and you're in business.
