Is the modern EE afraid of everything more then one part

No, the modern EE is cost, energy, effort and space conscious and doesn't throw 30 parts on a board if a single 1.000V, three pin SOT-23-3 reference is easily available.

Unfortunately I live in the Netherlands and I don't have that many resources when it comes to IC's and stuff.

In this thread http://mightyohm.com/blog/2010/11/where-do-you-shop-for-electronics/ someone mentioned RS, Farnell (aka Element14) and dickbest  :-DD for the Netherlands. And someone points to a list of 120 mail-oeder shops in your neighbor country Germany http://www.mikrocontroller.net/articles/Elektronikversender

Again, we first have to know what the TS needs.

Maybe 1.0V is good enough ( because of his limmited knowlegde I do not think he want up to 1 uV precsion ;-)  so probably your suggestion will be a usefull one)

The ADR510 is 1.000V plus/min 3.5 mV and if he is a beginner the sot23-3 can be a problem.

I never tried but I just read a IR led is a good 1.1V zener.

Oh cmon now ;) you can put SOT-23-3 on a 0.1" pad-per-hole perfboard. Its not the prettiest thing, but at least you dont need to buy an adaptor.

Hey, i solder 0603 by hand, but i have good eyes and a good solderstation. There are biginners with cheap bad solder, using S-39 and a 50W plumbers iron  >:D
