no you can not quit. but the Picket 3 is a better buy on Ebay. First do a search for Picket2 and read all on this site. You will need more than the Picket and Mouser does sell one, but there are kits for better money. I think go with a picket3 instead of a two or PM the people on the list to program PICs. Good luck and if you need links PM me. Good luck and have a great time.
