Welcome! What part of PA you from? Do you have any Lithium Ion cells and/or charger? Those will be a large part of your expense (only buy highly rated cells and chargers). If you don't want Li-Ions expense at this time you may wish to look at the UltraOK 4AAA light (which can also run on Li-Ions) - it just needs a little help in heatsinking.
