There are many factors in here:
You´re talking about a CX. They´re normally not ready to go if you get them off of eBay and such. Chances to find a fine one at a dealer isn´t that great. Most of them won´t touch them as trade-ins. But some do, so with some luck..
Why your own suspension and luggage? It´s not unique to find an eBay CX with hard luggage and all - just take your time.
Are you prepared to do anything yourself to the bike or would it be "key in and go".
Where are you planning to start your trip? Lots of CX-es in the UK and Germany. France too, probably. UK bikes seem to go for less money (and have had a tougher life, climatewise) than German ones. Swedish bikes cost more, Danish and Norwegien even more. About Italy and Spain I don´t know much, but I know a guy who used to go to Italy to pick up bikes from there to sell - also a couple of CX-es so probably worth the effort.
Do you plan to run the bike down to the ground, or care for it in a sensible way?
There are more questions..
Sture
Edit:
You should also consider the price difference. To me it seems that it´s easy to get a genuine low-miler for very little money over there. Not entirely so here. Most owners seem to have at least a vague idea of what their bikes may fetch. Others don´t. The trick is to find these...
