I'm the OP. Those marble strips are nice but they only come in white. Since our floor is dark they wouldn't work for us. We ended up going with wood. There was no molding of the right shape or height, especially since we were trying to bridge a height transition: the tile being higher. We bought ranch molding that was designed for window and door frames. If you are not familiar with ranch molding, in profile it has a slope: one side is high and the other side is lower. The installers has to shave some wood off the back to make it fit (to reduce the height), but that was their problem since they had promised they would come up with something nice for us and had not. We had them bring the wood right before the weekend and then we stained and varnished it to match our other moldings. On Monday they came back and installed it. The carpeting is a berber, and the edge is tucked lightly under the lowest edge. The high side butts against the tile/durock and a small caulk line is in between.

I still cannot locate a source where I can order a reducer or transition for the doorway where the vinyl tile meets the carpet. There are none I can find to match the Shaw Array Resort Tile Sunlit Sand I have. Mrobvious, who makes the Burmese Slate #23 please, The floor has already been installed and flooring store will come back and replace the cheap metal strip when I find the right piece as they don't carry anything for LVT. This is a picture of the doorway, cabinet color and LVT before it was grouted. Thanks! Can I use a wooden one or wood tone that matches the color of the oak cabinets there or would that not look right? This post was edited by tinker1121 on Thu, Oct 16, 14 at 5:56

You can do one of two things, if you don't want that strip. First, you can trun and tack the carpet at the edge of the tile with no transition (I don't care for doing this without having atleast a metal "L" strip to protect the edge of the tile) or, as you suggest, use a marble threshold, and butt both finishes up to either side of it.

"I don't understand what you want to do. Currently you have a carpet bar covering the carpet/tile transition. The bar is on top of the ceramic tile and covering the carpet. Do you want to remove this brass item and replace it with something else? Why would you need to remove the tile?" Hi, ron6519 -- sorry - I must not have explained very clearly. We don't have any ceramic tile. We pulled up linoleum and put slate tile down to replace it. But the metal piece is not on top of any ceramic tile at all. It's not on top of anything other than the subfloor. It butts up against the tile, with a slight gap. I don't think I have to pull the tile up (it is something that someone at Lowe's recommended we do... I was more looking for confirmation that we DON'T need to). Thanks, Sierraeast, I will try to find the flooring forum. There are so many forums here, that I think I have the right one but I guess I don't. Thanks though. :)
