So, I have quite a few basses but as of yet, I don't have a single fretless. In fact, as I think about it, I'm not positive that at any point in history I've ever played a fretless. But I feel the need to add one to my collection because... well, it's nice to have options. I keep hearing people saying about certain models "The side fret markers are in the wrong place." I don't want to buy my first fretless and find out that this is the case with my new purchase. So, TBers, how do I determine if any prospective fretlesses have the markers in the right/wrong place? Extra points if you can give examples of brands that have markers in the right places and ones that are totally off. (also, specifically wondering if Wolf brand basses are correct/incorrect) I want to buy a fretless that will make my transition as easy as possible. Thanks in advance! 
I've been looking for an excuse to get the magic markers out.
