Can't see why not a 555. Perhaps its edges are rather slow and so not much RF.
I'd probably use a 74HC14 schmitt trigger. One section with an R and C as oscillator, another section (or sections in parallel) as an output buffer. Will run on a pair of AA cells though obviously with only 3Vp-p output. This ought to be enough.
