Like mclina and Garyharris said, Harbor freight clamps come in an assortment, just as good as any clamps i have seen elsewhere and MUCH cheaper I bought 4 of the 18 pack small plastic clamps for 3.99 it is in a plastic tube on the clamp aisle. I think you get 14 small ones and 4 medium ones in the pack. They recently had the mini bar clamps for 99 cents each and they work great! just get what you think you need for your style of building. be sure and get or make some small 90 degree angles to help with ribs and bigger ones (like the drafting kind) for keeping other stuff staight. I REALLY like that kit!!!!! I would love to build one myself! oh get 100 or so each of the small and large T-pins from your local hobby shop too, you should do a build thread! keep us posted with pics at least please!
