I did mine at the start of the year. Newage cabinets are spot on and 9 months down the line, I'm still happy with them. Argos were cheapest for me at the time, but there are a few suppliers out there, Costco etc.
Only got single garage but will only be bike related, other sheds will take care of that So thinking of taking the rear 3m wall and doing a similar layout. Thnk these look good value http://pages.ebay.com/link/?nav=item.view&alt=web&id=371362773938&globalID=EBAY-GB
Thanks - I have also donated to Halfords - excellent buy! Can't take photo as garage too messy but no excuses now....
