Rated 4 out of 5 by from I'd pay double for one made of anodized aluminum.I've ready many times how crackable this thing is, so I'm treating mine with kid gloves. I use a 1" long bit to finger tighten the three screws that hold it to the router. It doesn't seem like much, but it's never worked loose. Every hole has been perfect, but I have to think three times before setting the thing down between cuts. A few pointers that bear repeating:1. Clamp the board you're cutting down to another board you don't mind cutting when the bit cuts through your working piece.2. Put a couple of countersink screws through the middle of the disk you'll be cutting out and into the abovementioned backing board. When you cut through, your guide hole suddenly becomes free floating. Preserves the edge on the inside and outside of the cut.3. Power tools are the perfect example of "You get what you pay for." Buck up for a good plunge router and a sharp new bit.

Rated 2 out of 5 by from Good jig but way over priced.I've used one of these and they work OK. The material it's made out of isn't super heavy duty, but it works. I was lucky and was able to borrow this from a friend. Parts Express is awesome, and I don't believe they mark this up a heck of a lot, but the item feels like it should be worth maybe $15 to $20. After all, some simple math a board and minimal hardware and you could make one for a few bucks that works. Especially if you make only a few different size holes.

Rated 5 out of 5 by from easy to useI like this sirkel jig.easy and fast to use when i want perfect holes for my drivers.

Rated 5 out of 5 by from Huge Router Bits!This thing is so nice. I agree, it adds control, stability. Also allows use of large router bits to mortise flush mount rings. The 1 3/4 inch hole allows you to see what you are doing, and cuttings to clear. This clearance make this Jasper different (way better) than models 240 or 400. I really like using a 3/4 inch flat cut, 1/2 drive bit with this (the 200) to mortise flush mounts. Perfect for 99 percent of my circles too.

Rated 5 out of 5 by from A MUST have tool for any DIY speaker builderI have both the 400 & 200 model jig. I almost always use the 200. Its larger size makes it easier to control the router when cutting a circle. Also the 200 model can be uses to keep your router flat when flush trimming a baffle edge etc.No matter how careful you are you never get a perfect cut with a jig saw. Please with the Jasper jig you can flush mount your speakers.One tip; I always go up 1/16 larger than what the speaker size is because making the hole exactly the same size won't all the speaker to fit. No matter what make a practice cut on a scrape, especially if your going to flush mount, to make sure you have the jig set up perfectly. You don't want to make a mistake and ruin your baffle with a wrong size cut.

We do not have that specific model listed but that does not mean it won't work. I would recommend contacting Jasper directly for a specific list of compatible routers.
