As deadeye said you can get away cheap if you want to but i wouldn't recommend it. Do yourself a favor and get an electric starter. It's really comfortable if you have a cranky engine. Especially the smaller ones. Get a good starter from the beginning. A 12 V battery is mandatory. An electric fuelpump is not a must-have but it sure is nice. I got a windshield washer pump from a scrapped VW Golf for a couple of bucks. That is the tank and the pump in one so you don't have to carry the whole fuel can to the field. If you get a powerpanel you don't have to have a cordless glowdriver which is more expensive than one with a cord. Plus you don't have to charge that ni-cad cell either.

This is a hopefully a onetime investment so I recommend you to spend a little now instead of having to do it again later.

Good luck!
