Batteries
What I would do is this...get cheap raw 3300 cells for about $5 each. 4 packs of 6 will cost you 120. IMHO, matching isnt the utmost importance, especially if you are starting to race.
Pick up a used high end charger for 120-150(I picked up my Integy 16x9 for $150, it's real easy to find the same deal)
Assemble packs and go rip em up
When I used to race, I have 4 race packs, and 6 cheapie practice packs, usually picked up used packs off of team racers or buddies for a good deal for practicing.
The more you keep in your pocket, the more to can spend elsewhere.
The fukyama packs are real cheap too....
