doubt this helps as u want a 1080p but i recently thought the same, till i realised that unless i used my pc i wouldnt even notice the definition, ended up getting a 32" samsung for a bit over 300
Samsung LE32A436T1D Series 4 32" HD TV + Freeview 1366x768 8500:1 1080i 3xHDMI Black - Ebuyer , that one but i got it on the cheap from some other web deal, if u really want a 42" 1080p ure gonna be looking at mid 500's to 600 in the uk, unless u want a refurb
tldr; 720p is fine unless u want ure pc/sit at a certain distance of ure tv
save ureself a couple hundred quid
that said if i had a job id have gone with the 1080p
