30D Repair or replace

60D or 7D would be the obvious choices but are you sure it's the camera. I had the same error on my 40D with the 17-85 lens and it was the wiring inside the lens that caused the 'communication' problem between camera and lens. I dumped the lens and got the 15-85 but also got the 7D anyway - a combination I use 90% of the time.

Any EOS camera will take the lenses that you have for your 30D (but any EF-S lenses you have will not fit on a 'full frame' sensor).
As Umberto says, the best camera to replace it depends on your budget. My default choice would be for the 60D which has the highest spec APS-C sensor that Canon currently has on the market plus a movable LCD for low level work. If you shoot a lot of birds in flight, the 60D is still very capable but the 7D is the state-of-the-art. If budget is too tight for the 60D then you could go for the 50D or 40D.
I started with the 30D and now have the 7D (though I still use the 30D) - most of the time I cannot tell the difference between pictures from either camera and bought the 7D purely for the functionality of the improved AF.

Thanks for your comments. I have a EFS 17-55 lens and a EF 100-400 and the fault happens with both lenses. The fault will even occur with no lens on and with no memory card in the camera. I take alot of pictures at Drifting (as both my sons have Drift cars) so I do need to keep the 100-400. As my 30D (which is a great camera when its working) has had a couple of problems I wonder if the 40D and 50D have similar problems. I think I will be looking at the 60D or the 7D.
All the best, Pete.

Current rumour is that there will be no 7D Mk2 and that the 70D spec will step up midway higher in the gap between 600D/700D and 5D Mk2/3.
I guess that would mean the 70D is likely to be at a higher price point than the 60D currently is.
Your decision is unlikely to be wrong if you buy now when you 'need' a camera rather than when you only 'want' one.
HTH
Don't forget that camera rumours are exactly just that and means that bungee jumpers can go down as well as up
:o)
