There is a SM who has designed some great T-Shirts on Cafe Press, but if that's not to your taste, how about a gift card to Staples or Office Depot for supplies? Or a great new flashlight, or (my favorite gift from a cast member thus far) a prepaid massage or facial coupon. A box of chocolates will never be refused, of course, or something that says the person (cast or blood family) took a minute to know me enough to pick something appropriate (nice cuz I have fairly atypical taste). OR even a heartfelt card expressing appreciation and understanding of hard work and time spent.
