[Elecraft] K2 Arrives - WTCPT question, DMM Question.

[Darwin, Keith]

The kit arrived yesterday.  SN 5411.  I'm still waiting for my magnifying lamp to arrive.  Then soldering begins.
 
With my WTCPT station, I accidently left it on for about a week.  I turned it off and put in a new tip (PTH).  When I assembled my mini-module, I found I had to dwell a long time (5-10 seconds) before I could get solder to melt.  In a few cases I felt the board getting warm.  I changed tips to my original tip (after cleaning it up) and dwell times dropped to about 3 seconds.
 
So what tip should I be using?
 
Also which DMM should I buy?  Is there one out there that is considered a best buy or a great unit at a good price (the cheaper the better)??
