In reply to sethmford:
I'm 6ft 3, big old unit at 110 kilos and for me, my weight was the first thing I took into consideration when I bought a touring set up.
I bought a pair of touring skis that were 100 underfoot to compensate for my weight. Gives me more surface area and I thought it would make me slower coming down, if that were possible, but I'm not complaining. I've also used them for a couple of days skiing in Germany on the piste with no problems. I'm not too sure how well the touring bindings would fair with weeks on the piste but they are very good.
I really didn't want to buy a touring specific ski, I wanted something I could use for touring and skiing but I bought some ex rental skis for £100 that I could use when I wanted to spend time just skiing on runs. For reference, I ski 175s which according to all the experts you meet, is too small for me but I like them and ski well with them. Also, I bought a cheap pair of Scarpa Denali XT boots which although not the most refined or modern boots, I like them and importantly they fit me perfectly and keep me warm.
I think £300 is not enough to get a decent set up but you won't go far wrong with something like this:

That to me is a bargain. You just need the boots :0)
