Wanted: Trying my luck:going clipless - helmet - bag / backpack(ala ortlieb)

Okay just trying my luck with three things that have been around in my head lately.

First I'd like to say that I have looked a bit through the classifieds but didnt really find anything matching. Maybe I missed your item?

I'd like to start to go clipless. Not much clue about it except what I have read on here so I was thinking that if someone has size 8 (my size for trainers)shoes, cleats and pedals all together and that he wants to get rid of it I'll go with it. As I am starting I want to stay cheap though. Let me know if you got one of those things.
Would be for commuting so as far as I have read the ideal would be MTB shoes. Not bothered between Time or SPDs tbh.

Then helmet. Just want to try to see if I get along with this as my commute has doubled and interested to test this. Not bothered with what it could be. Black or white preferred though. Not crashed obviously, not too pricey too. Not sure what is my head measurement , will tape it tomorrow but I should be S - M, I don't have a big head.

Also, anyone got an* bag* like the Ortlieb messenger or the SealLine Urban and would like to sell it ? Could be well used, not an issue to me. I was looking at a Bagaboo Workhouse some weeks ago, but I used to use a single strap bag and would like something else.

And finally, if anyone has a cheap 27.2 grey seatpost that can go down the seat tube enough for my petite legs. Otherwise I'll take the one a forumenger offered to me.

Wow. That's it !

I have this for sale

might help if we knew what size your feet are!!

Thanks dkmike. size 8, well at least my trainers. Should avoid in the future writing thread whilst being tired, it is long and not very straight to the point

sumo, what size? large as in the link? might be too big too :( PM'd anyway

Not sure what Hugh is about? Did I miss anything?
