I think it is better to have one or two guns that can do a variaty of task. I have a mossberg 500 that for the longest time I couldn't get the hang of then after boxes of shells I "became one with the gun" and it is like an extention of my arm now. My friends hate bird hunting with me now.

Getting familiar withyour gun is very important IMO. One gun you are familiar with isbetter then 10 disigned for different task, not to mention cheaper.
