I don't believe primes are that "general purpose." I think the new 28-105 would probably be a great lens, however there is this lens out there:
SMC-Pentax FA 28-105mm F4-5.6 Reviews - FA Zoom Lenses - Pentax Lens Reviews & Lens Database
it's a very good lens if you don't mind the slightly weird bokeh when subjects are closer than about 15 feet. There are half a dozen on ebay at any one time for around $100 USD. It's very sharp and has the FA colors and contrast. I used one for about 2 years as a gap filler between my landscape and telephoto lenses.
for the price of the new 28-105, you could pick up the older FA 28-105, plus the FA100-300 and maybe an FA50 macro. That's a decent starter 3 lens kit that would allow your to familiarize yourself with photography again and really highlight your personal style.
Once you have a better idea of what you shoot most often and how, you can start spending much more money on lenses that target your specific needs.

Just found this on the K-1 description site
It's not always/necessarily a function of the AF module. The AF micro adjustments are more designed to alleviate manufacturer tolerance issues. It's impossible to manufacture lenses and mounts to the exacting requirements that focal planes require. So each combination of lens and body will interact differently. You could literally get another K5 and you may have a focus adjustment of +2 with that same lens.
I have a couple lenses that went from +/- 1-2 on my K5iis to -7 or -8 on my K3. My FA28 and FA50 1.7 were spot on my K5iis but unusable (could not even determine if front or back focused at max adjustments) on my K3.
