[Elecraft] K2 Build Sequence Question

[Jon Perelstein]

I'm thinking of building a K2.  My thought is that I eventually want a K2 w/ 100 watts and SSB, but I'd like to take it in stages by first building a K2, then upping it to 100 watts, and then finally adding SSB.  

More specifically, I thought I'd do the following:

1.  Order the K2 and a KAT100 this week (I figure the KAT100 rather than the KAT2 given my intention of eventually moving up to 100 watts).  I expect that I'll also add the KNB2 at this point since things can be pretty noisy at my QTH.

2. Add the KDSP2 later this year (Nov/Dec) once I get some familiarity with the K2 itself.

3. Add the KPA100 around April 2009, which should be just in time for me to work with it a little before Field Day 2009.

4.  Add the KSB2 at some later date (probably sometime in the first half of 2010).

For those who have done something like this -- or at least thought about it -- are there any significant gotcha's that you think I should know about?  Is adding the KPA100 or the KSB2 very difficult and would you strongly argue against adding later versus build now?  Should I switch the sequence (e.g., SSB first, then 100 watts)?

Thanks in advance for your input.
