I've thought about pinbot for a long time but there is a healthy bait and switch mentality on these darn things. i gave up and went with Black Knight last year.
seems like they are realistically worth in the 900ish range around here (KC/StL to Minn, Omaha to Chicago)
but as soon as you start talking they really want more like 1200 to 1800.
there was a decent one at MGC in the 1200 range but it didn't sell all weekend.
Kinda looked dated next to all the other cool pins as competition. sad to say.....
