Question about lip sync? Necessary?

[df4801]

All ready to purchase the pioneer 1015tx for my front projector home theater. Then I read about lip sync, and the 1015tx does not have it. Is it really necessary? What does it actually do?
Its amazing how you can be all ready to pull the trigger, then you find out about something else! Thats it, after this, I am reading no more about equipment. LOL

Lip Sync delay

The additional processing and scalling steps used by most HDTVs, LCDs, Plasmas, and Front projector can cause the video to be delayed by a few frames which equates to 50-100ms. When the audio processing (from the receiver) gets to the listener before the video, this can cause the user to observe the "lip sync" problem. The lip sync delay accounts for this problem by delaying the audio for a perticular input by a user specified value. It is possible that a perticular projector or HDTV will have 'fast' video processing and not introduce a significant delay. Also, sending the projector its native resolution might minimize the delay.

I also plan to use my receiver with a front projector so I considered this feature a necessity.

This feature is starting to become standard on most receivers:
Yamahas in the last 2 years have it.
Denon '06' models.
HK 235 and up.
Pioneer high end models.
Onkyo ?

So if using the receiver with a front projector in which the projector will likely receive an input that it scales to 720p, it sounds like I need lip sync. Correct?
If so, back to the drawing board! I was happy to be able to get the 1015tx for under $400. Any suggestions on a comparable receiver under $500 that has lip sync? Thanks.
By the way, going with a 5.1 system and paradigm monitor 5/ cc370 setup.

Not on most Onkyos.

The Onkyo 802 has lip sync delay. Each year they introduce new models and migrate some of the features from the higher models to the lower models. I'm hoping lip sync gets in the 703 this time around.

Any one else have any thoughts on lip sync feature. ie. if needed with a front projector.
Now thinking about the yamaha rx-v1500.
