Thanks everyone for your advice.
Schaz, I ended up paying a bit more on boots than I intended to because I think you're toatlly correct that the most important thing is the boot. I'll probably still have the boots long after the skis are junked. I tried on a few without looking at the price and just picked the most comfy which also ended up being the most expensive lol. It's got some special gel in it that they heat and then you put it on for 15minutes and it moulds to your foot so all the time breaking it in is cut out. I got it for 40% off so it was still a great price for the quality of boot.
The guy who sold it to me has all his new stock coming in so he was pretty happy to clear a bit of the old stuff out.

ETA - Pat, I bought a unisex ski but it hasn't got the bindings on it yet. Can I get him to put it further forward or do they have to go at an exact spot on the ski?

I got adult's skis - I just can't bring myself to get a kid's skis even if they are cheaper. I only stopped buying my PJs in the kids section 5 years ago when I stopped working night shifts and put 5kg on.
