Sorry to hear of your misfortunes (no pun intended) Tarun. I got mine (avr230) from harman audio's ebay store and it arrived in pristine condition. No shipping damage that you know of? I don't know of anybody who runs a hk2005 so your'e guess is as good as mine. It might be worth a shot if you don't mind potentially paying shipping charges if you don't like it.
There is a gentleman on the avs forum that goes by the username of "M Code" that has a lot of firsthand experience with the digital path receiver. Might be worth looking into for some information. Or you could get a 635 and add a couple of mono amps from outlaw like bugbitten has done.
Edit: Here is a
link to the DPR2005 review at avs.
Edit again: Tarun, what do you mean by no osd? Does the 7300 allow osd via component video? I thought that everything could be accessed thru the remote without having to mess with the front panels?
