I've had no problems in Praha. beautiful city, good transportation, yes it's expensive in the center. I have Czech friends, go out and do normal events, don't spend all my time and money in the Casino's on Vaclave Nametski or with the girls on it's side streets.
Still, even my Czech friends say the most beautiful woman in the world are from Slovakia.
Sounds like the Tax situation and Expenses are good in Slovakia. You also have an offer of assistance and advice from someone who has already navigated the country. I would jump on that in a heartbeat.
