In reply to Gone for good:
All of the UK based companies are going to have to add their mark up before selling to you. You have to weigh up the piece of mind and reassurance of having all the information and access to it from a UK company.
From what I have seen KE are going to be good, but are much more focused on trekking and walking than climbing. Have a look at Adventure Peaks based in the lakes and Jagged Globe based in Sheffield.
They are both then going to use their in-country agents once you arrive. The other option is to contact the company direct.
Nepal=Sacred Summits very good
Bolivia= High Earth (Elisa the owner was outstanding)
Kyrgyzstan=ITMC very good
All of these companies will provide the back up and support of whatever plan/objective you come up with as opposed to going on a packaged climbing trip.
As when you go to a new climbing venue with just a guide book you need to be prepared to spend a lot of time messing about finding routes and areas. So you need to first work out what is important to you, getting up stuff or exploring.
Main thing is do one or the other not sit at home
