Well, you are going to spend very little. Switchcraft makes excellent RCAs that Shindo uses as well. They are very inexpensive and low mass. Great sounding, no nonsense.
The 3502 or 3507 should work. the 3502A may be a bit large. Have a look at the Switchcraft RCA selection at Mouser.com; they may have models that are even smaller in diameter.
