Your maths is a little off, two packs of Trakpower 3200's and a charger is £130, decent NiMH's were available for as little as £30 per pack so the cost to change is potentially more. Add a balancer and you are up to £160ish.
However, the ease of use and lifespan far outweigh the difference in price.
Bring on the list so I can make the change to LiPo!
