Tell us the sort of practical flash scenarios you are wanting to work with ...eg studio, outdoors, HSS, type of lights needed etc. There are many many Pentax users around producing professional quality flash results in all sorts of situations, so there is going to be a good solution for you, I'm sure!
I agree that for some more specialised techniques, eg multi-flash wireless HSS, there are more limited options than with Canon and Nikon, but it's all perfectly do-able, both automatic P-TTL optically with the Pentax own system, or now with a whole range of other brand HSS capable strobes and flashes, with the new Cactus V6II as 'HSS enabler'.
Let us know what you need to do and I'm sure the answers will pile in .... It's what we enjoy most around here!
