For your SME 3010-R I agree with Cello, pick up a Denon DL-103R. It should be an acceptable mass and compliance match and it's a wonderful cartridge for the money (<$300). You'll have to hurry, the 103 line is being discontinued.
I also agree with his advice to avoid used cartridges, at least until you have a little experience. It's easier to get burned with a used cartridge than any other component. If you know the seller that's different of course.
Your JMW needs a higher compliance cartridge. Grado's are a possiblity, but they're sensitive to stray EM fields, like leakage from the AC motor on your Scout. Some people have a hum problem with Grado's, some don't. They're also known to have a suspension issue: google on "grado dance" or "grado wiggle" and you'll get a million hits. Personally I can't think of a good reason to risk money with those risks. Dynavector, Audio Technica, ZYX, Benz and quite a few other brands make cartridges that would suit a JMW-9.
The Shelters mentioned by Hiradi would probably blow your budget. Certainly the 901 would, it lists for $1500. The 501MkII ($800) would suit your SME nicely but not the JMW.
Read the vinyl FAQ's on Audio Asylum for a primer on some technical issues. Not everything there is perfect or non-controversial, but it will give you a ton of information to chew on.
