Making your own can end up being quite expensive - but it is a good feeling when it is finally realised!

I use 4MS Row Power and busboards - inexpensive - trivially easy to install - zero problems - I have 4 of them.

There are definitely 'better' power supplies out there and you can easily spend a lot more, but these have served me well for several years now, well since they were released, whenever that was :)
