After much deliberating over the weekend, I cancelled the 18-135
Decided I didn't want a "jack of all trades" despite all the glowing reviews.
Have bought a 16-45
Couldn't bring myself to go down the heavy Sigma route
Now need to find something to replace my trusty 50-200
Thanks again to all

Yes great set!
Is gothography a word? If not, it should be!
Pretty sure we have seen number 5 before?

Oh, and as for leaning against a family member, never gonna happen!!

So.....
Firstly thank you all for the advice and opinions.
Much appreciated even though sometimes it may appear that i ignored them
Yes i was probably "getting unnecessarily concerned about f4" plus i think i may have lost sight of the objective - "Head off with the mindset that you'll achieve what you can achieve with that lens, don't over think it, just enjoy the photographic experience of exploring somewhere new (or different) - One camera, one lens."

As per above, things have now changed
So, after ensuring that my precious K200D is in fact ok i have bought a brand new DA 18-135.
It is heavier than i would have liked not as long as my 50-200 and cost rather more than i wanted to spend.
It does however fill my needs for the upcoming trip and also as a general walkabout lens after that
I just hope that it is as good as all the reviews i have read

Thanks again

Adam (not actually Les after all 😃 )

Sorry, not ignoring this
I dropped my camera this morning
Thankfully the K200D appears to be ok
The 50-200 not so much !!!!!

Need to have a rethink

Then what happens?
Can it be refurbished?

What about
HD Pentax-DA* 16-50mm F2.8 ED PLM AW
For 243 euros from Amazon.fr?

------- Edit -------
Nope, not the HD version!

So, here is where I am at currently

The 16-45 will cover my needs adequately apart from probably struggling in low light

The 10-20 will cover my needs because it is a hoover but it may possibly distort part of an image along with lengthening my arm

The 20-40 is an awesome but very expensive lens which may not be wide enough for my needs

The 2 versions of the 18-50 may also not be wide enough and would struggle in low light

Any other offers?

Thanks for all the input so far.

I am currently looking at the Pentax 20-40 at 300euros in very good condition.

I know there are wider options (thanks Spad and jonathan-mac) but i don't really want to get into fisheye/distortion territory

Don't hesitate to input more as i am not rushing since this is a LOT of money for me

In a good way?
