Agreed. You don't go there expecting the best or healthiest food, but it is pretty tasty food for cheap.
Anyways, as for PHXsportsfans' question, I'll use two games as an example.
1st:
I went to the Cubs @ Dbacks last August, and we sat at Fridays FR. It was $32.50 per ticket (not counting food) and a pretty good view if you can get tickets for outside, I wouldn't recommend inside, unless you like watching TV, as that's basically what you get until you say screw it and go walk through the stadium to find better seats.
Here is the view from Fridays:

2nd.
Then there was my more recent game, we went to the second home game of the year. Section 132 row 29 seat 12.
No Fridays and pure stadium seating, however there are concession stands everywhere down there, and if you get a ballpark hotdog, get the Arizona dog, it was really good!

All in all, I liked both, but too be honest, I liked the second game better. I sat directly in front of the worst, most druken Cubs fans ever up at Fridays.
At the Dodger game, the view was great, Reynolds' homerun looked awesome from that angle. The only thing that was annoying were the vendors walking up and down the aisles every five seconds screaming "Cold beer!"
Going on those two experiences I'd recommend getting stadium seats, but usually after about the 3rd inning you move around until you find the section you want. If you have more questions just send me a message on AIM.
