[sdiy] in need of a good bench supply (+/- 0-18 volts and 5)

[George Hearn]

The TTi (Thurlby Thandar) PL310/PL320/PL330 QMD or QMT models are absolutely
fantastic.  I bought a top of the range (£1200 new) PL330QMT on ebay for
£175 in perfect condition and will never look back.  Beware of cheap bench
power supplies, you may be disappointed!  One thing I have found is that
some supplies have very uncontrolled behavior during power on.  Some cheaper
supplies also do not allow you to individually switch DC and mains and I'd
avoid these.  
  The TTi supplies have 'Quad Mode' which means you can parallel for more
current, series for more voltage, tracking for split supplies or
independently operate.  George

I need a solid bench power supply that is NOT connected to my modular, and
has a nice case (unlike my home-made stuff) and doesnt suffer from
ripple,etc.
 
so I am going to be buying a bench supply. but wow, they are expensive.


my budget for a new or used bench supply is at most, 200 bucks.
 
I am a bit confused as to whether or not a +/- 0-18 or 20 volt output is
considered ONE output or Two.
 
obviously the 5v output is another out.
 
so am i looking for a 2 output or a three?
 
any brands or types to stay away from?
 
 
I was looking at this one:
 
http://www.web-tronics.com/dualout03x22.html
 
but from the datasheet (unless i read it wrong) it seems to have 2 +/-
outputs and a 5volt out, which is actually more than I need.
 
but it IS under 200.
 
thanks for any help
 
and if anyone has an extra bench supply they want to sell, well let me know
 
thanks!
