My Small Board has a Pedal Power 2 on it. It's great, but you fast run out of connectors if you need high current or high voltage pedals.
My large board has the Gigrig System. Power Generator, distributors and isolators etc.
It's not cheap when you get all the bits you need but it's been bullet proof and it will even power the most stupidly demanding pedals. It's a brilliant product.
I have lots of high current pedals, and at a rough guess a complete battery change on my big board would cost about £80. So I was very happy to use about 3 battery change funds for a Gigrig set up.
