I have a shortlist of three for my next TV. I'd appreciate any comments. Philips 32PW9617C for around £1200 Panasonic TX32PB50 for £1150 Hitachi C36WF830N for £1500 or suggest an alternative. I'd like great picture and DD. Should I be wary of buying from online retailers, with regard to warranty claims or just general dissatisfaction? Thanks.
