Here's a lot of different examples of grinders you can spend less than a fiver on one or over a ton all depends on wants and needs. With concerns about plastic bits breaking off and into herb I would lean towards a non toxic one i.e. metal or hemp or suchlike.

Google online head shop to find similar stores, I'd recommend my favourite from my signature but they are overseas and I'm sure you are in a rush to get one
Personally I use a hemp version of the diamond tooth cheap plastic ones, I just prefer the fineness of the grind compared to my 3 tier pollen catching metal ones.
I used the original S&B grinder for years, then when I went medical I got the notion that I'd start using dosing capsules etc so I bought the dosing capsule filling tool which fills 40 capsules at once, and since you need to grind like 6 g in one go for that, I got the XL.
Well, that didn't really last. Turns out I actually enjoy the process of grinding the little bit of flower you're going to vape in that particular session instead of grinding it all up once every week or so, so I've defaulted back to the original grinder at this point.
Storage wise the smaller grinder just fits in a case/bag etc so much easier than the large one, I haven't managed to find a decent space for the large one that doesn't annoy me. It's too big and round to fit into the square holes that usually come in most stash boxes etc...
The larger one is easier to actually handle for grinding (wider grip, less torque required to get the grind going), but more difficult to handle for transferring the ground bud to wherever it's heading (unless it's the dosing capsule tray) and to clean just because it's so large.
All in all, I'd recommend the XL to anyone who's going to stick to the dosing capsule routine more devoutly than I did, or who has motor issues/difficulty with a smaller grinder. For everyone else, the original is going to get the job done with less hassle overall.
