You could try placing a wanted ad in Astromart. Maybe someone has a cell of the right size he would be happy to sell to you. As for having one made, that could cost you a lot of bucks. I've started building a 15-inch truss-tube Dob and so far I spent 100 bucks just building the tailgate and flotation system for the primary mirror, and I did all the fitting, welding and shaping myself. You could however make a cell yourself however, but you'll have to pay attention to giving the mirror uniform supports to avoid poor views due to the mirror sagging due to gravity. High quality plywood and aluminum can be used to make a mirror cell, and you would avoid the expense of having a welder build the cell to your specifications. Below is a picture of my mirror cell under construction. If you do have a drill press and a DC stick or MIG welder, you can build a mirror cell out of aluminum, or a stainless or mild steel cell with even the most basic of AC welding machines.

If you're looking to get something made for you, "affordable" won't be in the picture. How much are you looking to spend? - j

Try Astrosky and Astrosystems.
I had these bookmarked, but I don't know if they're active. - j

You could call up Joe Palachek, who makes JStar cells. Ambrose Liao has been using a JStar 13.1" cell and seems to have been quite happy with it. He was charged $50 for it. Apparently Mr. Palachek doesn't have a website, but I have his cell-phone number, so if you PM me, I'll send it to you.
Here's a photo of the cell: http://lunarphoto.blogspot.com/2008/12/first-upgrade-of-coulter.html

Is it for a tube, or truss scope? They will be different. I had used a Novak cell for my 16" Newt. But I made one for a 16" dob I'm building.

DAR astro
This is definitely not $400, but they do offer a 16" mirror cell for a tube at $770 Canadian. The exchange rate helps out the USD a bit, but obviously not $370 worth.
Mirror Cell Kit
This also looks intriguing. $100 for a 16" mirror cell kit. It looks like he also does custom cells, but probably again for a very high price.

Hello,
This is my 16" mirror cell:
You can build one for few money. You only need the measures and talk with a metal carpentry.

You can make an equal area 18 point flotation cell with almost no tools. A simple saw and drill, some nuts and bolts, some felt padding and a few hours can make what you need. AND it will perform every bit as good as a $400 unit.
