@Crazy E trying to price out these trucks is a fools errand. They will always have varying pricing and I think honestly its really all about what you want to do with it.
If you want to wrench then buy something cheap and work on it. If you don't have the time to wrench, but have money, buy something complete like this $21k truck.
It does not seem like you are looking for a cheap LC, since both of the trucks you have listed are in the $20k range.
I am looking on Craigslist in the Bay Area and there are a bunch of FJ60s/ FJ62s in a very wide range of prices. The cheapest might be a parts car at around $3500 (asking price), but the most expensive one is $27k.

There are quite a few in the $7-14k range and every few weeks there is a new one going up. I was able to get my 89 FJt2 for $6k. I am another $6k into parts at this point and labor is pretty much all me ( so free, I guess).
I would stop trying to "value" the trucks out there and start with what makes you happy and what is within your means. If you have $20k to blow on a truck, why not get a "cheap" $8k unmolested truck and then put all the bells and whistles on that you want so you can make it your own? Otherwise you're really just buying someone else's dream.
