Thanks for the sound advice everyone - really, really helpful, and as a result I seem to have sorted out a plan for most of the gear in my list in the first post, apart from a few things. Trying to keep the cost down as much as possible, as it all adds up to well over £400, which is about £150 more than I had budgeted for!
Regarding winter cycling, could I manage throughout winter with a base layer, long sleeved Jersey and then either a gilet or a packable windproof / showerproof jacket over the top (such as the Montane Featherlite Velo, which packs up tiny so I could carry it everywhere, and gets cracking reviews)? If not, I could perhaps get a thicker long sleeved jersey such as the DHB Windslam Roubaix, which is very warm according to the reviews, and then use other layers as required.
Originally I was planning to get an
Altura Night Vision waterproof jacket and wear that over other layers in the really cold winter - but I guess there's nowhere to put it if you get too warm (as it isn't packable into a stuff sack) so I'm going off that idea. I don't need a 'proper' waterproof jacket as I won't be commuting - so figured a well-reviewed packable one would be better.
Also, does everyone simply wear Bib tights (full length) in winter? If so, any recommendations for inexpensive options?
Shoes - I really need some recommendations for good, inexpensive SPD shoes that I can walk in. Planning to get the Shimano M520 pedals (£20 from pedalon). Will probably need to get the shoes from my LBS though, for obvious reasons.
Helmet - spotted the Specialized Align for £20, down from £30, at the Edinburgh Cycling Coop. Seems to get very good reviews, I assume this will be good enough? Everyone seems to say it's very comfortable - I know I ought to try one on, but at that price, I think I'll take a slight gamble, can always send it back I guess. I know I'm a medium (54-60cm usually).
Lights - Edinburgh Coop are doing the CatEye EL130/TL130 light set for £18. Seems like a very good price, I won't be doing any cycling in total darkness (unless I get stranded!) it's more for switching them on in poor visibility conditions or at dusk, to be seen.
Track pump - was going to go for the JoeBlow Sport II (approx £30) as it gets good reviews. Then spotted the Bontrager Charger Pump at
Evans for £22, or even the Revolution Air Track Pump Sport at Edinburgh Coop - reduced to £9.99 ! Gets good reviews. Think I might go for the JoeBlow one though.
