It's the only one available now, I've paid less, and I would pay that if I didn't have two.
discussion about these I started here
You can wear out the original beryllium cantilever/microline stylus and replace it with another used one that pops up in the future,
or, new boron cantilever fits that body if one doesn't pop up
or, IF you are not comfortable risking buying a used stylus, but like AT's dual magnet sound and light 1.25 tracking, you can buy a used cartridge with a broken or missing cantilever and put a new stylus in it.
I like Boron if buying new, and I see they still sell 3 VMN Boron Stylii that fit these older AT150, AT155, AT160; AT440 bodies
AT-VMN45xML (microlinear/nude/boron cantilever)
AT-VMN50xSH (Shibata/nude/boron cantilever)
AT-VMN60xSL (special line contact/nude/boron cantilever)
You pay a little more for the 1st one, you get lucky with the price of a spare, it averages out, you really shouldn't wait IMO, start enjoying.

Do you have the few inexpensive tools and skills (or a friend with the tools and skills) to mount and align the cartridge?
