[Elecraft] K2 Build: Options Advice

[Dauer, Edward]

I see no disadvantage.  

I have built three, each of which has all of options you are considering.  As David says there are some parts that need to be unsoldered, and a couple where the through-holes need to be cleaned up for inserting something else.  Nonetheless, when I built mine even though I ordered the options at the same time as the base kit, I finished the base kit completely first, then went back in to add the options.  Two reasons -- first, if there were to be a problem somewhere I wanted to be able to analyze it in the least complicated way.  So, K2 first, test, then each option and its test.  Second -- it's a kit.  That's part of the fun.

    The disadvantage is that you will need to unsolder some components.  In 
    most cases, I think you can destroy the through holes, but there is at 
    least one case where you have to insert a new value in the old hole.
    
    There used to be a, third party, product, called UnPCBs, which provide a 
    minimal dummy version of most of the modules, but the sales of the K2 
    dropped to a level where it wasn't worth another production run for the 
    PCBs for this.
