I always wanted a Kuro and found an LX5090 going cheap on here, should be better than my Samsung as only just are people talking about the VT50 being close it them.
As long as it is a fair price then go for it. KRP's can be had so cheap these days I'd go for one of them. Whatever you buy, just be warned that it is likely to have the dreaded red tint to blacks - unless voltage adjusted. I wouldn't rule one out if it had been adjusted if it has sorted the red tint problem. Have a viewing first if you can and check for sparklies/pixel misfire/black rain side effects.
