I'm assuming, you are choosing one of the elmars because of their size and portability. In lieu of that, you should know you have a few other options.
If you search on that big auction site that shant be named, there are many lenses made by a lens creator called Miyazaki. He created a series of VERY small lenses. Japancamerahunter featured his lenses a few times. and I think there are a few distributors out there who are selling them.
If you are looking for portablility, these lenses "M.S. Optical" will blow any elmar or elmarit or summarit out of the water in terms of portability and cost. If you are looking for sample images, quite a few can be found on flickr.
