I can recommend this ebay seller: http://shop.ebay.com/merchant/tta_mem

He's got good stock, good pricing, great service (will combine shipping, responsive to emails,etc), and has been 100% reliable so far.

Uno bibs are $130 + shipping (now at $23 ). You should shop around, but know that this guy will deliver.

BTW, I'm 5'10" and 165-170# and fit comfortably in the Large FI.13 S5's, but find the Roubaix Bib knickers a bit loose in that size. Could also be the difference in chamois between the S5 and the bib knicks (Mille insert)
