Welcome, tommc! You've found the right place, though I'm not sure how objective we are about the R65.

I admit to having a bias—I bought mine in 2007 under similar circumstances, and for the same reason. (Maybe I should substitute "rationalization" for "reason".) However, I confess that I like mine so much that I'm reluctant to risk its theft or damage in the parking garage at the commuter railroad station, so I continue to drive a clunker car the 4 miles each way. If you can find an R65 to ride, I suggest doing so. I think you'll be impressed.
IMHO, your most important consideration is finding an R65 that has had a lot of TLC. Because of its age (25 years minimum, at least here in the USA) and the cost of BMW parts in general, you might find a major restoration to be both costly and frustrating. But the compensating factor is that it's still possible to find an R65 in good shape at a reasonable price, at least in my part of the country.
You didn't mention your part of the world. Our membership is multi-continental, but is more concentrated in certain areas. For that reason, you might find this site especially helpful. Check "General Announcements", "Chit-Chat", and "Trading Post" frequently—especially the latter. (Example: another message string on this forum, "Picking Up Britta Today", implies that an R65 ("Britta") will soon be available in the Carolinas.) Also, if you have access through membership or a friend who is a member, the BMWMOA web site's Flea Market has R65s for sale fairly often.
Keep in touch! I think you'll find us friendly and helpful, and many of us (myself excepted) actually know a lot about these machines.
Good hunting,
John
