I think it's important to understand the limitations first. A Pentax-M 50mm f1.7 is a great lens, but requires manual focus, M mode, using the aperture ring and metering with the green button. If you can't work that way, it's not a great lens for you. It may be worth just buying this one lens as an experiment, to see how it works for you.
Then you need an education on the lenses that work on your camera, so you can ignore the ones that won't work. K-mount lenses work without an adapter. Be aware of the Ricoh pin, which is a problem on a handful of lenses. A few lenses need to have the light shield modified or removed to mount. The M42 mount lenses also work with an adapter. T-mount lenses work with an adapter too. Other mounts can work with easy or difficult modifications. Tamron, Vivitar and Soligor made lenses with interchangeable mount systems that can work too, with the right adapters.
Buying lenses will be harder given your location. Shipping and customs may rule out some deals. You should also be aware of fungus and oil on aperture blades. They are more of a problem in the tropics.
Try to learn as much as possible about a lens before buying. Research is easy for Pentax, maybe harder for other brands. You should know if a lens is common or rare, how it compares to similar lenses and how it should work.
You should have an idea of what you need. If you know you need a great macro lens, and don't use wide angle a lot, you can stop looking at those cool Vivitar 20mm f3.8 primes and save your money for the macro.
Some lenses just aren't worth buying. If you buy a lot of lenses, you'll end up with enough old 70-200mm MF zooms, 135mm primes and film cameras to fill a box.
General is exactly what I need! Thanks

3) Go have fun!
I have one M42 to PK adapter coming to me this instance. I ordered it 2 days ago
..and yes, I'm having fun everyday with my 1.4. Not a day missed without taking a few pics with this gem
Originally posted by eddie1960 i would have snapped up an m 50 1.4 at that price, iif the speck of fungus was small it was still a good deal, but in a tropical environment fungus can spread quickly (store it in an air tight container with a silica pack though and it would likely halt the growth for now)
it would be easy to over expose at 1.4 in any well lit area (not to mention a bugger to get the right focus) easy to contend with by lowering ISO increasing shutter speed though.
an smc m 50 f1.4 in my neck of the woods is rarely available for less than $80-100 (and is frequently more) if it is fungus/oil/haze free unless you are lucky.
A Ka will be even more (in fact they are usually so high i makes more sense to look for an F or FA as they are close in price sometimes to where people value the Ka
this should give you a quick read on current values
New and used pentax 50mm, Lenses on eBay.ca Will you believe if I tell you that yesterday in my local internet-based marketplace (quite similar to this site's) a SMC M 50mm 1.2 an a M 50 1.7 popped out and sold for merely $100 for the 1.2 and $30 for the 1.7 (prices are still negotiable) ? The seller puts it at noon and sold only 2 hours later, and I missed it for just like 30 minutes! God, I just hate to be me!
The 1.4 itself is quite common here. At this moment, there is at least three or four M 1.4 lying around still waiting for buyer at $40 - $50. I don't see AF primes, though.
