I got rid of my Q220 with folding cart, propane hose, Weber weather cover, and an empty propane tank for $150.00 cash on CL about 2 weeks ago after I landed my Q300 off CL.

I purchased my Q220 shortly before Weber upgraded the Q220 with the electric ignition, so I'm basing my opinion on a Q220 that was purchased in late 2007 before the model upgrade. Based on the one I owned, I would discourage anyone from buying it to use as their primary grill. At the time, I was living in an apartment and I didn't have much room on my deck, so it worked well given the limited space I had. Over time, I found that it was underpowered unless you followed the lighting routine to the letter, and even then, it wouldn't get much above 300 - 350 degrees.

One thing to consider is how you are planning on using the Q220 when camping or tailgating. I looked all over Jacksonville, Florida and could never find the narrow propane bottles. I tried to use a Coleman propane disposable bottle that was fat and squat, but it wouldn't clear the stainless steel hoop ring in the back of the unit where you mate it to the regulator.
See stainless steel hoop on left side where regulator hose is at. You have to be able to clear that hoop.

The one time I took it tailgating, the Q220 fit perfectly in the back of my BMW Z4 convertible with the trunk closed and the convertible top down, but the 20# propane tank had to ride in the passenger side footwell.

Here are some food p0rn shots off the Q220. I took these using my old 2006 Nikon E5600 point-and-shoot, so these pictures haven't run through any Instagram filters to make them look better than they were when I snapped the photo.
Here are some shrimp:
