content: Hello,christmas is near and I thought of buyng myself an electronic load: it's a piece of equipment that sometimes I need and that I don't feel comfortable building myself.I narrowed down my choice to three candidates (based on my requirements):SiglentSDL 1020X-EITECH8511A+BK Precision8542BThe problem is that I don't understand why the BK costs double the price of the others, am I blind looking at the specs? Also the Siglent (which is the cheapest, albeit by 7€) seems to me to have the best specs.What am I missing here?Thanks!

content: Location Location Location . Facility cost , labour cost , quality control cost , service cost , etc. Although B&K equipment may have a higher price tag you'll probably get better construction quality and better customer service . You may also experience longer intervals between calibrations . Which can be important to a company that can't afford unnecessary down time. Less expensive equipment may be better for the hobbyist or student that won't be using the instrument for 8-10 hours, 5 days a week.

You pay premium price for that.Itech is more like Rigol , but is fully as durable/Bingo

content: Maybe add the Maynuo M9712 to the list.http://www.maynuo.com/english/pro.asp?tid=25There are some older threads around here that discuss the lineage of early DC load designs and supposedly sometime after one of the early foundational designs was commercialized the designer either went to Maynuo or made the next version of the design for Maynuo. The M9712 has been around for several years and it doesn't have the pretty looking UIs of some of the newer models but it has been a solid performer with a pretty high degree of accuracy, so if nothing else it might provide somewhat of a benchmark.

content: Go for Maynuo! BK only rebrands stuff, no added value, only price increase.

content: I think if you trace it backward for about 8 years you will get to Maynuo.https://www.eevblog.com/forum/testgear/first-use-of-maynuo-m712-electronic-load/msg275266/#msg275266This is not to take away from ITECH or other brands and models. Probably have to study/compare the current specs, prices, support arrangements, etc.
