When you buy a charger, you should get one that has a proven track record with reliability and confidence. when i started racing i bought a duratrax digital intelipeak, it was a great starter charger, then the PS blew and got it RMA'd, but I broke down and bought a GFX. I loved it.... but then I started turning and breaking in motors, and running 1/12 as well as 1/10 TC and purchased a second gfx. now it is great. yes they are large, but they are proven and reliable... and I use the duratrax for the practice packs...
Someone mentioned to look for used stuff... I agree on that if you cannot buy the charger you want. You can get the Turbo 35 BL or Stealth BL with powersupplies for a decent price right now with a lot of people selling electric going nitro this time of year...
Just something to think about.
