Also this may be a daft question but I looked at this

The power supply costs about £70 on its own, or £50 with the board . Is there any advantage to having something like this rather than just plugging multiple normal 3 pin plug 9v adaptors into a normal power bar/ plug adaptor thing (the sort of thing you get from Woolworths for £1.99)? Apart from the obvious less wires thing. :?
It will probably be be no better than using a couple of reasonable 9V adaptors, from Maplins etc. with a couple of daisy chain leads to spread the power around. Personally I would go to Maplins rather than Woolies, as the quality of the PSU's will be better. They are about a tenner each if I remember rightly. I run my whole pedalboard from two such Maplin adaptors, and it's REALLY quiet. I would see no need to change except for neatness. I have run up to 6 or 7 pedals off one PSU, no problem (as long as the PSU can provide the milliamps required for all the pedals).
A very important point about Multi power supplies like the Gator G-Bus 8 is whether each output is actually isolated from each other. If they are electronically isolated, then it is theoretically the best scenario, and is effectively the same as giving each pedal it's own dedicated PSU. The Gator G-bus 8 does not claim to have isolated outputs, therefore one has to assume that it probably doesn't have them. Multi isolated output PSU's are generally fairly pricy.
Another point to mention is that some pedals (Line6 pedals in particular) seem to be
much quieter with their own dedicated power supply (or their own isolated output from a multi supply) compared to sharing a daisy-chained supply with other pedals.
