Going from a ventless to vented W/D???

We currently have an older Splendide (6190 model) that is backed up to an inside wall thereby requiring a non-vented model. It works just fine but, as others have noted, the drying is compromised and the water consumption is higher.

Has anyone had success in finding a new model combo unit that can be vented out the side rather than directly out the back. Alternatively are new models more efficient that the older design?

Thanks for any input.....However not interested in seeing vented vs non-vented comments since I already know the limitations.
