mmcray and Brave,
Good so far, but I really suggest that you get the newer 9230 from Progressive Dynamics.
91XX are good converters, but to be great, you need to add the "Charge Wizard" and extra part...
92XX Have the Charge Wizard built in.
Actually any good multi-stage (like 3 or 4 depending on how it is counted) will do well.
There are also other brands like Iota.
Both Iota and PD are American companies and warranty or repair is simple.
