Ok so I have been a ham for about a year now. I took my dad's advice and bought an Icom IC-7000 last year as my first rig. It is alright but I am starting to see where the rig is lacking. I am going to sell the rig, the auto tuner I have with it and the Heil mic that I have for it. I figure that on flee-bay I can get about a grand for the rig and accessories. I am going to return an HF Auto from Palstar that I bought a week ago because it is, well not ready for prime time. So I have roughly 2500 give or take to spend on a new rig and will obviously need a new mic as well. I use a Heathkit sb-200 just did the Harbach mods and am fairly happy with that, I will at some point upgrade that as well (I am obsessed with 160m cw) and want to run QRO on 160.
I want a radio that I can at some point run dual receivers to listen to the both sides of a pile up. And want to be able to have a bit more selectivity on receive.
From the specs I have seen, I think the Elecraft K3 may be the way to go. I know that I am going to have to live with a radio without a secondary receiver for the moment. But love that I can upgrade the radio as time goes on. I have no problem building the radio so I can save a few bucks and get a few accessories for it.
I have also looked at getting a Ten Tech Orion II and see that it is a fairly option packed radio too, but it seems lacking in the receiver specs.
My dad has an Icom 7800 and I like the radio, but don't want to shell out that much money for a rig, and am not sure that it would satisfy my cw habit.
Is there any advice that you all would give me, I am willing to save up for a bit to get a bit more expensive radio, I don't mind getting something used, like a 7600 or a Icom Pro III with the inrad mods.
I will use this radio for DX and contesting predominately. In the seven months I have really been active (since getting my general I have 154 countries 95 confirmed) and hope to get my rear-end on the honor roll asap

.
My antenna right now is a homebrew 160m Windom and with neighborhood beams and verticals are out of the question.
The only radio that I am absolutely against is the Flex radios. Software defined radios are not my cup of tea.
Any input at all will be greatly appreciated. Thanks in advance.
