Have an opportunity to buy a used LEIGH D1600 DT jig with bits and a vacuum attachment..I learned that this 16" model was discontinued several years ago and then closed out at retail ....I have much respect for the LEIGH company as well as its dovetail jigs..Although generally expensive, I consider them the top DT jig available..However, this is an older model in an odd size of 16"..Should I walk away? What do you guys think is a fair price for a used unit of that model? Your opinion will help decide to pursue or not..Thanks in advance, Jerry
