Question:

I want to buy a high value Dado blade for my table saw. I want to build some shelf and closet organizer out of MDF and I want to inset the 3/4" MDF into a 3/4" dado.

Suggestions? Where to buy ? Model?

This better than using the router with a straightedge to make the dado cut ? What's better?

I guess I invested in anger and frustration. I refused to buy quite a few things as I didn't think I would use them again.

Took WAY longer though.

Router vs table saw will depend on how much you need to do. I will generally use a router if there are only a couple pieces to cut or the pieces are very large and might be difficult to get through the table saw. If I'm going to do several pieces or the pieces are smaller, then I'll use in a table saw.
A while back I purchased a rather nice dado set with grand intentions of using it on almost every project. I think I've used it twice.

One thing to watch out for is a short arbor on some less expensive table saws. My first had a very short arbor and I couldn't use a full dado set.

This one is probably the best value that I know of. It has all the shims you need to set it up for undersized plywood cuts.

Is it solipsistic in here, or is it just me?

I've used the router a few times and the results were good. I haven't used a Dado before, at least not since I was a teen. This is one area am lack experience with, but it seems handy for making shelf and a closet organizer for the laundry room.

As long as your router isn't underpowered and your router bits are decent, your router should easily take care of MDF (very soft compared to ply....which is more difficult!). Make sure you have a quality straight edge as your route.

I've used dados on my table saw...and the struggle of changing the blades out and watching out for the arbor is a pain in the tail end.

MDF makes a bunch of nasty sawdust...good dust extraction is a must.

Where dado blades shine is when you need an ultra-precise dado groove. You can dial a size down to the closest 1/32" on some sets. If you really want quickly repeatable close fitting joints, then dado blades are definitely the way to go. I got a Freud Diablo 8in stacked dado set for $100 that has served me well over the years.

Getting that kind of repeatable accuracy with router bits varies. There are special router bits that are sized specifically for plywood and the like and if you have those bits AND they match up with the thickness of plywood that you bought, then you simply can't beat that. But in my experience, there's simply too much variance in sheet good thicknesses between batches to really count on just one size router bit.

A far more accurate way (possibly the most accurate) is to build a router jig that has an adjustable width (one of many examples: http://www.woodsmithshop.com/downloa...bledadojig.pdf). In this case, you just stick your actual mating board in the jig and then route up one side and down the other to get a perfect match. Setup definitely takes longer if you are doing a lot of joints, though.
