I got a stereo memory man recently and its pretty sweet. Quick question about it: in the manual it says not to use any power adapter besides the one supplied. Are they just saying that so nobody using the wrong voltage adapter? Like, if I used a different 9V adapter would it actually harm the unit?

I want to use it with a pedalboard which is why im asking. Like, the powered gator tote or something. Any other recommended powered pedal boards for less than $200? I just need room for the memory man (about the size of 2 regular pedals side by side) and 4-5 regular sized pedals.
Are there any cheap power adapters if i just made a pedal board? Because those voodoo ones are like $150 and i may as well just get a gator for $100 if thats as cheap as they get.
