content: The purchase price for used Lambda power supplies fluctuates wildly. If you absolutely needed one immediately, you can find them on Amazon, Digikey, Mouser, and most test equipment resale websites for $1000+ (new obviously) there are 6A and 12A supplies on eBay for $500+ (used). Checking sold listings, a non-functioning 6A model sold for $125-ish a few months back. A working unit sold for $150-ish. They're not often available as a low starting price strait auction so the ending price could be in the low 100s up to a few hundred. This is based on the auctions that I've watched over the past couple years from my automatic eBay search.So, I know this doesn't really answer your question but they're worth the price someone is willing to attach to them. This is why I prefer trades, since we all have like-minded interests, someone may have something they don't value much but I would value quite a bit. Putting hard dollar (pound?) figures on these takes the fun out it all. If these were common, easily available, with plenty on eBay and plenty of people looking for these exact items (think Agilent 34401A multimeter), I'd just sell them on there for the average price range they seem to fall in. With these supplies, it would be better to wait till I can find someone who knows they're quality and would value them.If someone has an item they want to pass by me (suggestions for what Im interested in, in the top post), Im all ears. Also, Im not opposed to adding cash on top if they feel its worth more to them then the supplies are.Hope that makes sense.

content: I have been looking into these for a while. If only you had a 60V version... The downside is no front posts.edit: how is the fan noise? Is the fan temperature controlled or always at max.?

content: Its a constant speed fan. Its as loud as my new Siglent waveform generator, If you've ever heard one of those. Not as loud as most system power supplies but not quite as quiet as a new Rigol scope (not too far off though).I agree, posts in the rear isn't ideal. I had always intended to build up a platform that screws on the bottom and extends the rear posts to front banana jacks, but I never found the time. I've seen people do something similar with a small floating project box.

content: Added the PACE Desoldering Iron. Wiling to take offers for straight purchase, although I'd prefer to find someone with a half-rack sized DC Load for trade.
