c-tek either 5 amp or 10 amp would be my choice.

These do both types, google them

I think I read on here at some time that an 'ideal' charger is one that is to get one with Amps at least around 10% of the Amp Hour capacity.   

I have an 8 Amp Projector smart charger and it does ok with our 100amp battery.   I bought it on price though - around $100 - and used an Ebay buy it now with free postage printout and had the local SCA store price match it so I could pick up that day.   Price seems to increase exponentially with the higher Amp chargers.   The larger the Amps on the charger the faster it will charge.

If you're going to buy a charger, then get a decent sized one.

15A min, but 25A would be better IMO.

The smaller units may suit your current needs, but you'll eventually outgrow them.
