D30 is rather old now (2000 and 3MP) and although not entry level at the time, it has been superseded a fair bit to make £250 far too costly for it
For a little more you might even get a second hand 30D ( 2006, 8.3MP) which would represent excellent VFM as it betters it in everyway
The entry level 400D is perhaps in a different class but even it or the 350D would represent better VFM IMHO
What is your max budget?
