As I'm starting to immerse myself into film again after nearly 30 years I was wondering if I might get some suggestions for a handheld lightmeter to use with my old Yashica Mat (and any other older cameras I may have a hankering to use )? Or, on the other hand, will my meter in my Pentax MX or MESuper work fine, other than the fact I'll have to carry it with me?

I don't want to spend a ton of money (like to keep it $100 or less if possible), and I don't plan on ever shooting portraits or any type of studio work. Right now I've got an old Walz Coronet selenium meter that's fairly close to my MX if I set it's ASA at 1/2 of whatever the MX is set at.

Thanks for any help!
