You can get stainless ones, but only for the smaller tanks. They are also normally expensive.
What you should probably get the 2502 reels, they are adjustable as well, which saves a lot of money if you ever have to process MF.
IMO, jobo reels are normally of good quality as long as you keep them clean. I prefer stainless over plastic when im developing by hand, but they are worth giving up for the convenience of rotary processing.
