content: That display of yours sure is expensive, considering ones that look exactly alike costsubstantially less.The divider (I assume you mean distribution amplifier) can easily be built for $30-40 (this includes a professionally fabricated PCB).The case looks like it was made from one of those metal project enclosures ($30 tops). You just need to drill and nibble the holes, apply some stickers.Add $50 more bucks for the power supply and microcontroller board and you are basically done.I would understand if you said you added $100-150 for your work, but this is ridiculous.You want way too much for the stuff you are offering. This goes for all of your eBay ads.

content: Dear DaveIf you think that you will do it cheaper, then please prove it.I did not add here any labor costs.But it is like someone who speaks never did anything with DIY electronics.What are the prices? I'm always open to suggestions - prices, but that never came.So what?the same execution unit housing cost me $ 100 (laser cutting)PCB - 70 $Cost elements - 220 $Power Supply - 30 $

content: I was doing the best parts of the deviceIt has to work a long time - years. I do not like modern Chinese products - two years and into the trash.But it does not save much. After the display is not only a "display" but the communication module with TRIMBLE.you'll save on the display can $ 50 ....

Also, the eBay listing doesn't show any divided outputs? Do you mean the output line drivers for each 10MHz output? In which case, that's also vastly overpriced - a stable low-phase-noise output stage doesnotcost $37/pop. And I can reliably divide 10 MHz down to whatever you want for less than $15!No, these prices are way out there; you may possibly have paid this for your items, but they're sure as hell not worth it.(And as for working for a long time: As long as you buy genuine parts and generously overspec them, you can expect 10+ year lifetimes without even having to buy anything made outside china.)
