Question about some older pentax equipment??

I have a friend that has some pentax equipment and would like to get rid of the unused items. Got me to thinking that maybe I could put them to good use.

First item is a set of Pentax PK #1, #2, #3 extension tubes. Would I be able to use these with either 50mm or 100mm Pentax macro lens and get even closer?
What would be a fair price?

He also has a couple of lenses that sound tempting.

1st is Vivitar 28mm f2.8 that looks to be in perfect condition. Again what would be a fair price or should I not even consider it since it's not pentax glass?

2nd lens is a Pentax Image 135mm f2.8, also appears to be in great shape. This lens looks really nice. What would be a fair price for this one.

I really don't have any background in the older stuff and I know that there are a lot of you that really like the older glass and I see how fast it goes on the marketplace.
Any guideance or suggestions is greatly appreciated.
Thanks in advance....

All lenses that will mount on a newer digital camera will work, but some are more desirable than others and this affects their price. One of the key things with older lenses is their ability to receive aperture control automatically - such lenses (such as the Pentax "A" series) and other similar designs are more desirable for the newer digital cameras.

Once you have identified the exact model number, you can browse the Marketplace here (look at the sold items too) as well as other auction sites. Seeing what others have paid recently is your best guide.
