If you haven't already checked out Schluter's web site, then do that or phone any tile wholesaler and ask if you can snoop through their Schluter catalogue. They may be reluctant to do that because the wholesaler will think you're wanting to cut out his retailers and buy directly from him, but assure him that that isn't your intent... you just want to get ideas on how to deal with your particular tiling problem.

The Schluter "Quadec" profile is a simple and basic edging strip that you can use around any ceramic wall tile, and can also be used right at a corner to have tiling on one wall but not the other:
The Schluter "Jolly" strip is very similar, but it's smaller so that it can be pressed into use around materials other than ceramic tiling. (Your tub surround, for example)
The Schluter ECK-K profile is a basic stainless steel self adhesive corner that can be used anywhere, not necessarily with ceramic tiles.
