Hi, I finally decided to get a proper road bike.
My budget has slowly cret up to the 1500 bucks range and now see that there are quite a few left-over 06's in this range. I haven't been able to ride em yet but want to narrow down my list a bit (or maybe get new ideas) before I drive to the shops.

I want something comfy and fast for century rides and such....not racing (yet)

Here's my list:

KHS Flite 900 msrp 2200-->now about 1600 (ebay around 1200)...top of the line, kinda unique, but too racy?

Specializd Tarmac Comp-->1500 LBS
Specialized Roubaix---> 1800 LBS

Bianchi 928 --->2000 LBS (1600 ebay)

Cannondale Synapse ---> 1700 LBS (but sold out!!) trying to locate another 06 but can't

I haven't looked too much at Felt/Giant/Schwinn/Trek but nothing against them...just haven't been turned on by one yet.

Please advise.

Thanks
