Portable air con unit - any recommendations?

[VelvetPatch]

Hello lovely geeks - input welcomed.
My (3x4) garden cabin is hotting up and I'm currently exploring portable cooling or air con units - what a minefield! Nothing professionally installed mind, just something I can retail buy,plug and play when needed (mostly after a client just to cool & circulate air before next one). My cabin is so well insulated (fab in winter) but alas opening a window just doesn't do enough- arctic blast needed!
Anyone got one/ can recommend one /had experience of using one?
Any feedback, do's, no-no's warmly welcomed before I tackle this 'ere minefield alone!
Thanks lots
Sal x

I had to get a portable unit when i was in Oz, do not get ones that you have to add water to, everything in your cabin will get damp, makes the air very humid. The ones with a vent/tube that you can put through the window work the best.
