[sdiy] switching power supplies?

[Derek Holzer]

I've been researching PSUs again, and some upcoming gigs in North 
America have me looking at switching PSUs. My main spec priorities, as I 
mentioned on earlier threads, are ±15V, about 1A and fairly small size.

Curetronic here in Germany have the following on offer:

http://www.curetronic.com/curetrbau/neubau/power.htm

Power supply: [+/-15V][1,6A][AC Input 85-260V]
Protections: Shortcircuit-Overload-Overvoltage-Overtemperature
Size: 105x60x30mm
Price: 29,50 euro+shipment

I've been told that switching power supplies can be very noisy, so my 
questions would be:

1) Given that this is advertised on the webpage of a fairly respected 
synth manufacturer, should I take this PSU seriously in the absence of 
any other spec (I've written him for more info but haven't gotten a 
reply in a few weeks)?

2) Has anyone actually used this or another switching PSU successfully?

Happy holidays!
