Title: Someone please explain why these are priced like this...
Post by: cidcorp on November 11, 2013, 05:08:47 am

I've noticed this before, but never gave it much thought. 

Why are these supplies sooooo much more expensive than others on eBay?

(sorry don't know if the links will work correctly - so listed item number after link)
http://www.ebay.ca/itm/USA-Brand-Precision-Lab-GQ-A305D-Variable-30V-5A-DC-Power-Supply-w-CV-CC-mode-/290627598340?pt=LH_DefaultDomain_0&hash=item43aac13804 (http://www.ebay.ca/itm/USA-Brand-Precision-Lab-GQ-A305D-Variable-30V-5A-DC-Power-Supply-w-CV-CC-mode-/290627598340?pt=LH_DefaultDomain_0&hash=item43aac13804)
ITEM NUMBER: 290627598340

http://www.ebay.ca/itm/Precision-Lab-PS305D-Variable-30V-5A-DC-Power-Supply-/310295629869?pt=LH_DefaultDomain_2&hash=item483f0f902d (http://www.ebay.ca/itm/Precision-Lab-PS305D-Variable-30V-5A-DC-Power-Supply-/310295629869?pt=LH_DefaultDomain_2&hash=item483f0f902d)
ITEM NUMBER: 310295629869

I'm assuming because they are both from the same seller that someone didn't read the list price correctly as I'd expect this Bench Supply to go for 1/10 the price (ie: drop the last zero).

Just confirming that there is no other reason it could be so much more, well unless it's a lot of 10...lol.

Told seller a month ago, they ignored my message.

I'm looking for a new dual or triple output power supply, at least a 30v 5A max, and one of the 3 channels can be a fixed 5v.
I've been using a Micronta Adj Dual-Tracking Supply from Radio Shack (bought when I was alot younger) and it's been good to me, but
I need something with a digital readout...so I'm shopping around.  I think $200 or 300 is going to be my price point... if anyone
has suggestions.

Thanks
Chris

The eBay seller ran out of stock of those particular models.

If they close the sale page, when they  have the model in stock again they'll have to open a new listing and they get charged $0.5 or whatever the eBay fee is , the "More than 10 available / 16 sold "  or "More than 10 available / 82 sold"  text by the "Item quantity" gets lost  (some buyers will actually be convinced to buy from a seller who sold a lot of units compared to one with new listing) and so on.
It's just easier for them to adjust the price to some ridiculous value.

I find it amazing eBay are so slow on the uptake.

Well thanks that explains it perfectly.

I just discovered this myself on an $818.00 I.C.. 

Maybe this also explains crazy prices on some used test equipment.  I guess the take away is to mostly rely on prices of sold items to establish fair market.

Also, they might get lucky and sell one to some poor fool!
