It's really up to what you like.

I like a matching set so I would say get the matching dryer but really any dryer will do the job.

If you think you would use the "steam" option then sure get it but really think about it. The "steam" option is just for freshening up fabrics. It is NOT a substitute for an iron.

If you wanted to freshen up something now with your current dryer you can achieve the same results but throwing a dampened wet towel with the dry items you want to "freshen up".

I personally don't see the point of a steam dryer.

Best of luck and hope you get a good deal and are happy with any decision you make.
