EOS-1D Mark IV

[George Slusher]

Canon has two different models with a full-frame sensor (one less expensive than the 1D, one more expensive)

So true--5D Mk II @ $2700, 1D Mk III @ $3700 (Adorama shows $5,000 for the Mk IV), and a mind-blowing $6,114.95 for the 1Ds. (For about the same, you could get the 1D Mk III and the 5D Mk II.

There are four current models with 1.6x sensors
(one in each line, from one-digit to four-digit), so pick one of those
if that's what you want.

There are actually 5 models: Rebel XS (1000D), XSi (450D), & T1i (500D); 50D; 7D.
