I am in the market for my first 45deg Lock Miter Router bit and at first I was dead set on getting the Whiteside bit, but after watching some videos and doing more research I discovered Whiteside does not offer a setup block or gauge for their bits. Other companies offer these, so I was wondering if it is worth going for a lesser bit but spending more overall to have the setup block/guage? Or is the straight edge method good enough to provide alignment.
Infinity sells a gauge that at least appears to make setup foolproof, but it could just be a good marketing video.
Whiteside ~$80 on sale
Infinity ~$80 not on sale + $34 for setup guage = $114
Thoughts or experiences with the above bits or others?
