Yes PPC is the easiest to setup but it may not give you the returns you are looking for.
Have you thought of an affiliate setup instead/aswell? If you tailored it to include say big uk outdoor shops etc like cotswold or go outdoors as I'm sure most vistors to this site would be interested in, then you could get some big returns from sales (as you know a lot of outdoor kit/clothing is frickin expensive!).
A couple of the main UK affiliate network sites are:
http://www.clixgalore.co.ukhttp://www.affiliatewindow.com/http://www.webgains.comCheck them out (if you haven't already done so), the returns from sales can be quite high.
I guess it all comes down to whether you have the time/effort to go down this path, from the sounds of things you don't but it's worth a look...
Good luck and I will start clicking the ads when I see them
