In reply to Mr-Cowdrey:
I was steered away from dynafit bindings for my first touring set, whilst they are a lot lighter, you're much more likely to break your knees if you fall.
Don't know where you're based but it's worth getting boots from somewhere which will (1) let you take boots back as many times as it takes to tweek the fit and (2) where you'd be prepared to travel for that to be a possibility. Spend the money on getting a well fitting boot, save cash on 2nd hand skis, buy & sell while you're figuring out what you really want.
After struggling with ill fitting second hand boots a few times, I
I got my boots from backcountry UK, its a 4 hour train ride to Keighley for me but well worth the trip. I've been back twice for slight adjustments to the fit. the adjustments involved heating boot then stretching them. Also grinding the insole thinner to allow more space.
Also if you're planning to work on technique on piste a bit more before going off piste, then touring kit is often not recommmended to learn with, as it's generally harder to control & can hinder development of good technique.
I would also agree with Paul Atkinson. tuition first, kit later. Tips for quailty but affordable tuition are: Evolution2, AAC(UK), Eagle ski club.
