[Elecraft] Time to take the plunge...

[NZ8J]

Due to circumstances beyond my control I find myself with 5 or 6 weeks of
VERY idle time on my hands.  I've pretty much decided to order a K2 with
some accessories in the next day or so and work my way through it. I'll
probably only be able to put in 60 to 90 minutes of work at a time before I
have to let my old eyes and body rest for a few hours, but I figure I'll get
through it eventually.  I had heart bypass surgery last week and now will
have plenty of free time on my hands during the recoup period.  Anyone know
what serial numbers they are up to, I assume they are shipping kits with
serial numbers over 5K by now?

I have read over  the soldering tutorials  and info on the Elecraft site,
but don't specifically see the one lb rolls of Kester Solder that I have on
the list:
Kester SN 60OPB40, 66/44 rosin core solder. Dia .031
Kester Q13852, Alloy = SN63, Core = 66, Dia .031, FLUX = 254

Anyone familiar with these particular Kester versions?

thanks
