May as well wait for 3D TVs...
None of the 120/240 hz LCDs are 3D read and the 2 Samsung plasmas which are 3D ready don't come in 1080p.
If you don't care about 3D and are on a tight budget, then no matter what you choose 50/60hz LCD or 120/240 HZ lcd or Plasma...you will have a TV that is prolly the best TV in your house. Don't let anyone convince you that you need to spend 2000 bucks on a 240 hz TV or you won't get a quality product.
