P-mounts... there are some good possibilities here. I like Shures, and have an older Radio Shack/Shure RXT6. This is RS's version of the Shure M111E. This was one step down from the V15 series and an excellent cartidge. It uses the N111E (and some others) stylus that has the "dynamic stabilizer" (brush).
Ed Saunders has a used RXT6 and used M105E (same) with new replacement stylii right now, he has one of each.
You can also look for a MP94E, which is the P mount version of the M94E. It is out of production, but not long. You may still find them occasionally.
And there is the lowly M92E. You could save the stylus that comes with it as a backup and sub a better one such as the M97xE, which fits and works. Ed Saunders will have some N111E replacements ($50)in a few days, complete with brush stabilizer, and has some N97EJ replacements now ($30).
Other sylii that work in the Shure M92e, M94E, M105E, M111E, M111HE, and RS RXT5, RXT6 are: N92E, N94E, N97ED, N97EJ, N105E, N111E, N97xE. So there is a range of stylii you can use.
So, you can find a N92E as low as $25, and plug in the N111E, N97ED, or N97xE, which you can buy for about $50.
