I use the 1.4X-S on my 300mm f4.5 FA & all my shorter focal length lenses.
When I last researched this I believe the 300mm f2.8 required the 1.4 X-L.

3. The Pentax "xs" converters (as in "Pentax-A 1.4x-S, 2x-S) are designed
to be used with most focal length lenses. The "xl" variants ("Pentax-A
1.4x-L, 2x-L") are designed to be used with specific longer focal length
lenses. They have a projecting optic on the lens side that will interfere
if you try to fit them to the wrong primary lenses. I believe there is a
manual available on-line from Pentax which describes which lenses are
compatible with which converter.
4. I've seen the A70-210/4 Macro listed on Ebay for around $100, and on
good reseller websites (like B&H and KEH) for around $190-200. I sold
mine for around the latter price (can't remember exactly...) in EXC++
condition with case and caps.

1. Asahi is to Pentax as Nippon Kogaku is to Nikon, the old corporate

Takumar is the equivalent of Nikkor for screw-mount lenses. For K mount
lenses it denotes the cheaper consumer lenses without full SMC coating
(Like Series E, but of lower quality, most Series E lenses were gems,
most Takumars weren't).
2. yes, via an adaptor. You use the lenses like a K/M lens, via
stop-down metering after enabling a custom function.

Takumar?
2) A salesman at a store told me that I can use 67 lens' on my istDL,
is this true? If so, how well does it work?
3) What is the difference between the Pentax xl and xs teleconverters?
4) How much should I expect to pay for an A70-210/4 in good condition
(not mint, not trashed)?
Thanks for helping out the newb.
