I've found a dual current-limiting variable-voltage DC power supply. It does 0-30 Volts and up to 3 amps on each channel. Only problem is it costs $300 
Is this a reasonable price for a power supply?
If this is an unreasonable price, where do you recommend online for purchasing power supplies? This isn't an item I feel comfortable DIY'ing by the way, so I think I'm going to break down and buy a power supply sometime soon.
I'm going to be doing some automobile work so a DC power supply I could play around with inside would be nice. Might be cheaper to just disconnect my car battery and take it inside for the night since I won't be drawing that much current.😕 But of course I've saved up some money over the last few weeks so I have to find a way to spend it 🙄

power supply prices
Hi...
I suspect this is for a new one ?
I deal in surplus and depending upon the name
surplus ones working can be bought with both voltage
and current adjust for about $100-150 and might be found
on ebay. I've had some and have sold them used surplus
working at those prices. Good names to buy....
Lambda, Kepco and Sorenson. Good luck in your quest

$100 could build it, $50 and even much less if you're a good scrounger 😉
If it's a techy piece of lab equipment, the extra money may well be worth the precision of the output, who knows...(but audio doesn't need .02% regulation so who cares 🙂 ).

A very reasonable price.
Do you need a dual for automobile work? You could find some cheaper ones if you do not really need dual voltage output. If not, check also Farnell psu's in second hand. Very solid gear. Very heavy also.
AST Global is in PA
check their auctions on EBay. Bid Service is in South NJ -- they sell a lot of used power supplies -- most of what they sell is semiconductor manufacturing and test.
