 I picked up a Masterbuilt dual door propane smoker #20051311 which Sears had on sale.  Yes, I've been reading the various threads regarding the numerous modifications all of you have been recommending.  Assembly was easy and very painless.  My initial observations during assembly and initial fire up is:

1. Though the flame is nice and blue, I can tell that at the lowest settings, it's going to be way too hot to reach temps below 200 for smoking fish which is all I do.  Thus I'll need to figure out how to tone it down.

2.  Door needs a seal.

3.  I will be installing a smoke vent with damper at the top.

4. Water pan is way too small

5. Chip pan is a joke with such big slots allowing direct contact of the flame to the wood.

Speaking of wood, is it best to use wood chunks instead of wood chips?  I've been using Smokehouse's wood chips in my Big Chief electric smoker with great success but question if it will fire up to easily in a propane smoker.

For now #1 is my highest priority.

When I first got my GOSM I could not get it below 250* until I installed a needle valve, I could then get it down to 185*. I wanted to go lower to smoke jerky so I took the side burner from my gas grill and replaced the factory GOSM burner with it. It is about 1" small in diameter and now I can get down to 135* easily. The needle valve  also allowed me much more control over dialing in the temps. 
 
Just ordered the Bayou Classic 5HPR-30 48-Inch LPG Hose, High Pressure Regulator with needle valve from Amazon as you had recommended in your original post.  Very nice.  Thanks.

I would go bye a gas store and if they have a needle valve. That should let you reduce your gas flow enough to get to the temps that you want.
 
Biggest downside to the Masterbuilts IMHO is the burner size. The one in my XL is too much and the cabinet is huge!. They use the same burner in all of their gassers. I feel bad for the guys with the smaller ones. I will say the single biggest improvement I have done was the thermostat control. Now I can do 140 degree smokes with a bigger BTU burner bar, as well as hit the high temps, 400+
 
I just purchased a Masterbuilt Cookmaster propane smoker. I would be interested to know how you converted it over to natural gas. Our BBQ is natural gas and it sure is nice not having to check propane bottles all the time.

Honestly, the easiest thing to do is to remove the regulator and hose from the valve assembly, and plumb the NG line to it. You will find alot of people drilling out their orifices, but in my experience, the Masterbuilt burner burns too hot anyway. The NG will not burn as hot as the propane, but we are talking about smoking low and slow, 325* tops. Give it a try and see how it works. If it's too cool, you can aways drill out the orifice to make it hotter.

Reconsidered the Bayou regulator hose setup and just received their needle valve instead.  Will install it after I get a couple fittings.  Might still find a smaller burner if I can't get the temp down to a more reasonable level for fish smoking.
