i love my viking #1+. i've had it almost 20 years and the only problems i ever had were my own fault.
what were you looking for that you think this doesn't have? was there something else you wanted? if it fills your needs and you think it runs smoothly and the lessons are unlimited then why are you second-guessing yourself. sometimes our first instincts are the ones we SHOULD go with. if there is a service center nearby, then i don't think you have anything to worry about. in fact, it sounds like you did good.
i think that most people who review online are the dissatisfied ones. the ones that are deliriously happy don't bother. so you can't tell from reviewers.
just enjoy and feel lucky.
