For stuff like this, why don't people just set up their own donation site? The target audience isn't necessarily off-put by other steps, and you can get past the kickstarter fees.
Out of the goal, that's 125 pounds. How many man-hours do you think it would take to set up the site, test it, secure it, etc? I can't see that ever being worth it for relatively small goals like this! And that's before you even consider that folk are probably more likely to feel comfortable donating to a kickstarter, since they already have an account etc.
