While I don't know much about the Trek (don't have one), I can tell you the Raleigh is a GREAT riding bike (got 3). Build quality varies a bit on them though... The Raleigh is very comfortable, yet still feels sporty. Some people even preferred them to the Pro for racing years ago. They're not as stiff & agile as the Pro, but much nicer to ride long distance. Raleigh did make an International in 53cm ctc. You absolutely want the Reynolds 531, and NOT 501. They're certainly not the same grade of tubeset! On the Raleigh, expect to pay anywhere from about $300 on up.... Really perfect examples sell for around $750+, and I imagine a NOS/NIB example would go for around $1500 on eBay. Components were all Campagnolo Record (Nuovo), except for Weinmann brakes. While I don't know about the Trek, an International is a known Classic that you'll love. Chances are though, that the Trek will be less costly.
