First if you value your stuff dont buy a CHEAP charger. even though lipos have come a long way if you mistreat them buring charging you can start a fire you cant put out.
That said an inexpensive charger that is one of the safest is the Core from Schumacher. I have them as well as several that cost over $300 USD. I like it better than my high dollar Schulze and I think they are just as good as my Balance Pro's from FMA Direct. I personally know the man that designed the permaters of the charger and if I did not know him I would never had touched it because of the price. But it is a top line charger.
I have the UDC 20 but the UDC 10 is cheaper but wont charge at as high of an amperage level.
