your on an island where everything cost more.. and no idea if your on a built up one or the garden island..
it's a few days before christmas. if you can get to a sears(no idea if there is one, can't remember and really wasn't looking to shop when I was there.. tho we did buy from the wayland galeries and sloan.. but anyways.. I'd go get the biggest tool kit they(sear) sell that you can afford.. if no sears local.. you can order online, but shipping will be a killer.. lowes/ home depot has kits to, if there isn't a sears..
a set with ratchets (1/4 drive and 3/8 and 1/2") with sockets, wrenches and screwdrivers, pliers and vise grips.. would be a good start.. gearwrenches are the best thing since sliced bread..
it's the holidays so everyones got these sets on sale..
if you have a sears local but they don't stock them you might be able to order whatever kit you want and have it shipped to store for nothing.. and pick it up..
good luck..
