Hi K.,
I worked part time at a record store for nearly 10 years, and so I have to say, if you love any of them, keep them. With LPs, you aren't likely going to get the value you feel your special ones are worth.
If you look around for a good turntable because you want them to spin again, you'll likely find one. Talk to a reputable place that does repair on turntables and sound equipment, or look on eBay. Technics has quality, dependable turntables. We love ours.
You could donate them to your local goodwill, too. Do you have a local music shop that also deals with records, or the nearest major city might have a place. Here in Portland, at least half the music shops have LPs offered. They sure aren't dead here. I have quite a collection myself of stuff I will never, ever sell. I just wouldn't get what they are worth to me!
