i have an e-station BC-6 charger and I can charge up to 5A my lipo's without problems. 1A will take very long like you say. I found the Bantam and Estation charger very reasonable priced on Ebay and some online stores in Hongkong. They are often used by Heli-guys som you might look for one. Good luck!
