I'm not sure if external pumps are more expensive, but I would guess that they are. I think I've seen people use maxi-jet powerhead externally, so maybe they can lean both ways. Ask at your LFS, or look around online.

If as the days get warmer you find that your chiller is running most of the time, and maybe still not keeping up, you can greatly ease the demand on it by insulating your tank so the room heat can't warm the water as quickly. I use 2" thick rigid insulation panel (from Home depot or a lumber yard) to help keep my bimac tank at about 60 degrees. I cut pieces to fit under my tank, and on the back (sides optional). It makes a huge difference, especially on a glass tank (acrylic transfers a lot less heat than glass).
