I just had to get a new charger because my older (but top of the line in its day) Tekin 5A peak charger, blew up at my last race. My budget was also about 200$, and the best charger for 200$ is the:
Integy 16x7v6
it can do 6.5 amp charge, and a 30amp discharge which is the key. Ask all the big time cell matchers, and they will tell you in order to get the best performance out of your 3300s, you need between 5.5 and 6amp charge, and 30 amp discharge. You can also set all your cutoffs etc with this charger too... real nice.
There is a new in box Integy 16x7v6 on the classifieds board here for like 170, there is one new on ebay for like 170, and I bought mine right from speedtechrc.com for 189.
