I sold my VW85 recent and bought a new RS45. The former had a new lamp and went for $1,500 toward my upgrade, so $1k is a great price if you can look at it first. The latter just has more sheer horse power and slightly better contrast and sharpness, but rather obese.
In terms of upkeep, the Sony lamp is about 2/3 less. Quality wise, I still prefer made in Japan vs. China. The JVC's new remote is cheap looking. You can watch the JVC during the day, but not the Sony.
BTW, I did not buy the JVC for its 3D feature; could not care less.
