Turbo 30 is an old charger made by Competition Electronics. Thier newest charger is the Turbo 35 GFX, about $420 new. You can find old Turbo 35s and Turbo 30s for around $300 and under respectively.
For the price of $200 you cannot go wrong with a Integy 16x7 V6. This charger is absouletly awesome for the price. Not to mention it does not need a power supply.
