Most people have never had battery issues. Like many I use Eneloops and couldn't be happier. Before that I used several other brands and they were OK too.
"the camera body is effectively dead"
I am sorry to hear about that! Mine worked fine until I dropped it off a waterfall... and even after that it was OK, though the viewfinder was mucky. I have never heard of the battery compartment failing but anything that can happen will... eventually. If it is under warranty get it seen to.
"I had a fatal failure on the K100 that required a warranty replacement of the main board. Currently I have had no issues with either the K10 and K20 bodies. But I am lossing faith in Pentax. "
I would lose faith with a company that didn't honour warranties. But not the other way around. Every brand has failures and Pentax is no different. If anything, Pentax cameras are built to take a lot more abuse than other brands at the same price point.

It also doesn't switch off once switched on - I have to open the battery compartment.
Luckily I was able to claim under my insurance.

Some occasional random stuff at The Photographers Block: link
If this is the case then it should be a quick and straightforward repair (ie. cheap), but probably one that only Pentax would undertake. Why not give them a call and see what they say?
I had this problem with my GR-D and Ricoh replaced the fuse free of charge, despite it being a year out of warranty. Obviously Pentax aren't obliged to carry out work for gratis (and it might be a more complex job - I have no idea where it would be located on a K100D) but if you ask nicely you have nothing to lose - the camera won't work as it is...

I guess this camera is long in the tooth now, so is it worth getting it repaired, or is this a sign that it's time to move on. Or do I go back to my ME Super and film?
For goodness sake don't start using film again. That would be a bad thing. I get the occasional dud CD but I don't dust off the 78s!
Best wishes,
Andrew
