Is there a lot of choice out there?
Marcia,
It might save us a lot of time to know how many 25 foot sailboats are being produced new these days and/or what you are looking at (other than us doing your research for you). If you have a shortlist, that'd be great.
Catalina makes the C250, the C25 as a new production boat ceased years ago. Hunter probably. Compac maybe? I really can't think of any more after looking through a few sailing magazines. In that size you would be hard pressed to find a wheel except for the C250 with an outboard.
OK, our work is done, buy a C250!

They also have a great website:

Other than cost (always a consideration) going from a 23 to a 25 may not get you much in the way of significantly increased elbow room. We went from a C22 to a C25 which doubled our volume and made the C25 feel like the
Titanic in comparison (traditional interior) and standing headroom under the poptop with the enclosure was a pure luxury, although we took our old engine with us when we moved on up.
So, my question back to you is what do you think you'll "get" by going up only two feet? Do you sail on a lake where there is a reasonable size limitation?
