Still hesitating because i KNOW there ARE 7D's with focus problems....
There probably are a few 7D that roll out of the factory with actual AF problems... Just as there probably are some with bad shutters or metering systems that sneak past QC inspection, too.
But the vast majority of "problems" with the 7D are...
1. People who buy it but don't actually need it's features and don't have the experience to use it well...
2. People who don't take the time to read up and learn how to use it.
Very few "problems" track back to the camera itself. Sure, there are bound to be a few faulty cameras. But It's more often the person behind the camera who is at fault. 7D has another layer of complexity in the AF system, lot's of opportunity to set things up wrong and get in trouble... Which people are oh so good at doing and then sometimes blaming on the camera. It takes some time and effort to learn to use the camera well. It's usually best to set up AF as simply as possible and learn to use some of the enhancements a little at a time.
I would ask what you plan to shoot with it... Sure, 7D can shoot most anything, someone will respond. But if someone is planning portraits, weddings, landscape, still life... Generally mire sedate One Shot AF mode things like that... With 7D they're paying roughly $500-600 premium they really don't need to spend, buying features they're unlikely to use very often. If you are in AI Servo shooting action/sports a large percentage of the time... Well, this is the camera's forte and the extra cost might be money well invested to get the results you need. There are other nice features of the 7D, such as an upgraded shutter (rated to 150K clicks, as opposed to 100K on the 50D and 60D)... 100% viewfinder (which adds to the camera's size and weight, it's actually a little heavier than the full frame 5DII)... 8 fps (vs 5 fps on 60D, 6 fps on 50D)... fairly customizable control layout... some additional sealing for weather/dust resistance... Micro Focus adjust feature (which the 50D has, but the 60D doesn't... what was Canon thinking?). It uses the good, newer Lithium batteries - LP-E6 (same as 60D, 5DII) - which are probably good for 35 to 40% more shots than the earlier BP-511A (50D). The active matrix focus screen is a neat feature... but takes a little getting used to... You don't have as much feedback that AF is working, when shooting in AI Servo, so you have to learn to trust yourself and the camera a bit.
7D designers seemed to assume a fairly advanced user. It is Canon's most pro-oriented APS-C camera to date. It's expected that its users will want to give the camera more input and already know their way around a DSLR. Look on the mode dial... No "Running Man" icon (or the "Mountain", or any of the other Basic mode icons) Instead there are three user programmable "C" modes. Even images out of 7D seem to need a little more experienced user... the camera uses a relatively strong anti-alias filter so RAW files need more sharpening than with previous models.
7D is sort of a "1D Mark IV Lite". If you can see yourself using a 1D4... If that camera would be "the ultimate" for your particular type of shooting, but perhaps is just impractical considering it's price, then the 7D is a less expensive, somewhat scaled down option.
