@ nuficek:
You read the shortcomings of the LJ60 but your budgetary constraints may limit your choices, as you said. So you might just end up with exact this airplane.
The good news for you may be, that there are numerous people in Germany who have quite a lot of experience in operating this airplane (not me!). And there are operators and maintenance facilities which can tell you a lot about it.
Are you on an AOC or do you intend to operate it yourself?
PM me, I'm sure I can send you a few names and numbers.
