These phones work well but suffer from the normal "broken/cracked screen" fault, caused by impact and/or overheating. I've determined that for �7 or so its possible to repair this fault, however it requires very precise soldering of sub 1mm pitch FPC connectors.
Detailed here is the repair procedure.
Removing the old screen requires carefully detaching the glue and bending the panel's FPC backwards and forwards until the copper breaks. DO NOT pull on the connector as you will lift the tracks and create a paperweight!
Be careful not to use too much heat, or you may lift the tracks.
Make sure it is correctly centred using the two index holes for precise location.
Be careful not to bridge contacts, if you do use solder wick to clean up and resolder.
Then replace the previously removed metal EMC shields as shown here.
I have noticed that occasionally the panel doesen't exactly fit, however this shouldnt matter in most cases.
Enjoy your resurrected E250 :)
