I love to cook with wine. Sometimes I even put it in the food.

Are the PS 900 tips interchangeable with the SP200? I plugged in
a few model numbers for SP200 tips into the OK web store search and
nothing came up.

That just gave me an idea, I have some worn out Weller tips,
I may just saw one of, and drill a hole in it to make a hollow tip.
These old tips also fit in my newer temp controlled Voltcraft soldering iron.

Yes but which one(s) pay him?

I really hope he works for the other side.

I just recently bought one of these for $100:
http://www.circuitspecialists.com/prod.itml/icOid/9751

It beats dicking around with a soldering iron, which is what I always used
to do.

My mini-review from S.E.R.:

Using the one of standard single nozzles it came with I was able to remove
a 44 pin PLCC with no problems. Tried using the same nozzle to remove a 84
pin flat pack, but this didn't work, so I borrowed a nozzle specifically
for that package from the place I work that has a Hakko and it worked
perfectly. (Good to know that Hakko nozzles are interchangeable with this
station.) I checked its output temperature with a thermocouple and the
readings were within 2c of the set temperature of the station. No lifted
pads or circuit board damage so far. Overall for the $100 price I'm quite
happy with the station, and shipping was fast as well.
