Which power supply you should get is entirely depedent on your particular needs. I am personally in the market for a very thin power supply (hopefully no thicker than about 1 inch/25.4 mm) to fit under my travel board. It needs to have a total power output of at least 2000 mA @ 9 VDC, with two ports that are capable of at least 800 mA.
There are three power supplies I've identified that will work:
1. CIOKS DC7 - funky proprietary cables, 660 mA per port, so I would need to use Y cables to boost current capacity for 4 of the ports, making for a huge mess, unless I make custom cables for it. Internal primary power supply means only an IEC cable to power it, though.
2. TheGigRig GenX14 - expensive, but probably the neatest and cleanest cabling. No Y cables needed, voltage selectors are physically lockable.
3. Mono medium power supply - only 6 ports, 500 mA each, so four of them go to Y cables, one for a single digital pedal, and one to daisy chain 4 utility pedals. One of the ports has a voltage selector that doesn't lock into position, but it's doable if I goop it up with some silicone sealant to prevent it from being accidentally moved. The cheapest solution of the three.
If money were no object, I'd just immediately go for the GenX14, because I'm planning on using a solid flat board, and because the GenX14 only has jacks on one end of the cables, I can just drill small holes in the board where I actually need the cables to go through (with grommets, of course), and cables can be sized exactly to length. Other than price, the one thing that does give me pause about the GenX14 is that it uses a proprietary 24 VDC external power brick.
Since money *is* an object, I will probably go for the Mono, because it's the cheapest and less messy than the CIOKS DC7 for wiring, although it does require an external, proprietary 24 VDC power brick, as well.
