well I bit the bullet and after much agonizing I ordered the v2500 today from etronics.com
I finally decided I was close to having spent $200 in time trying to determine if it was indeed worth $200 more than the 5790. The last bit of agony however was over the MANUFACTURER's warranty, non-existent when purchased via the net. However I was told that etronics would warranty the unit themselves and the Philips warranty was also available so I purchased the 2yr (actually 1yr ext.) for $50 after talking to the folks at Philips and being assured that there would be no problems with the etronics warranty in leiu of a Yamaha warranty. If anything goes wrong I'm hoping it goes wrong in the second year as Philips warranty make use of "local" service centers and would probably mean no shipping required. we'll see. it should get here by the end of the week.
Next items up: cables, dvd player-recorder, hdtv tuner, lcd tv. any suggestions where to shop or forums to peruse (in addition to this great site) to educate myself would be most welcome.
thanks,
dave
