If you need Europe, just look for the EU-DEM, a new product that is a fused version of ASTER DEM and SRTM. http://epp.eurostat.ec.europa.eu/portal/page/portal/gisco_Geographical_information_maps/geodata/digital_elevation_model/eu_dem_laea http://www.eea.europa.eu/data-and-maps/data/eu-dem
You may want to take a look at the patched SRTM DEM from CGIAR: http://srtm.csi.cgiar.org/ Although it still contains the same intrinsic errors and limitations in coverage as SRTM, it is at least void-filled.
An improved version of SRTM data can be obtained from http://www.viewfinderpanoramas.org/. Coverage can be looked up under http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm The creator has put special emphasis on manually filling the error on icy parts of the world as described here: ...
I am not sure what resolution you are looking for, I assume high. But if you are wanting global coverage, you should looked at GTOPO30. It is low resolution, but it is global coverage.
In my opinion both ASTER and SRTM are maxed out. Nothing can be computationally done to improve the data. ASTER just has too much noise and SRTM is just very rough data. If you are going to spend money I would get the data that ESA is acquiring right now: There is a new data available here: http://www.astrium-geo.com/en/66-geo-elevation-and-dem You can ...
