Ok folks. Hopefully some of you are in the know when it comes to this kinda stuff.
I need a bench power supply, and it needs to put out the amps. I have some peltier projects and other things I'm doing, and as you know they suck the juice.
Anyway, my budget is ~125$.
I've kinda narrowed it down to two choices. I can get a nice 0-30V, 0-6A digital power supply for 125$ shipped. It comes with a 1 year warranty, which is a bonus. The other bonuses are the small size, digital readouts.. the downside is only 6A, although that should be enough for most everything. But what concerns me is that.. it's only 100 bucks. It does appear to be directly from a distributor, so maybe they're just offering near-wholesale prices.. but similar units sell for ~300$, which is what they say the list price is... hmm.
Then there's this HP 6427B supply. 0-20V, 0-15A.. which is excellent. The downsides are that it has no warranty(although its industrual, so it should last forever). It's huge and heavy.. and it has analog meters. It's only ~70$ right now with less than 2 hours left in the auction.
Part of me wants the "cool" new small digital unit, and part of me wants the output and proven reliability of an industrial unit. But then on the other hand, maybe the HP unit is on it's last leg and will die in 6 months and I'd be left with no recourse.
Gah! What do I pick!?
Edit: Ok, I decided to go for the HP unit.
