Switching from single action to double

Rich,

There's not much I can add to what has already been said.
It all boils down to what is comfortable to you, or what you think you would like more. Some like the color cup on top, some like it on the side and others like it below. It is a choice you will have to make but we can try and help if you are not sure.

I own both siphon-feed and gravity-feed and like them both.
I have never used a side-feed model so you will be better off asking Greg and Jim about that.

I just purchased the Omni 6000. Check out my resent post to get an idea what to look forward to with this airbrush. http://www.finescale.com/fsm/community/forum/topic.asp?TOPIC_ID=15837

Bottom feed,side feed, gravity feed- it's a matter of personal preference. Bottom feed gives you more paint capcity and takes more pressure to use. Gravity feed holds less paint but are easier to clean and better for detail work-in my opinion. The Omni 6000 side feed is a good combination of both. Although it is a side feed, the cup is a gravity feed cup-as in it doesn't have to pull paint from below the needle. Its kind of like a gravity feed with the paint cup on the side instead of fixed to the body. Either gun you choose is fine, its a matter of personal preference.

Like Scott, I too have a 200 which I now only use for large areas that require a lot of paint or Future. I recently got an Omni 4000 gravity feed for detail and smaller areas.
The two complement each other nicely.

If you get an Omni 3000 all your bottles and feed caps from your 200 will work I have a 200 and a 3000, and I use them both. I actually got the 3000 to replace the 200 but they both have their place. The 3000 is a bit more difficult to clean but I feel like I have much more control over the paint flow. When I need detail I use the Omni. When I'm just spraying parts or shooting Future I use the 200.

As to your question, I think it's a matter of personal preference. Any of them will doa good job at what we paint.

I'm sure mikev will respond --- he's one of the resident experts here.

In the mean time, see my comments in the following thread - http://www.finescale.com/fsm/community/forum/topic.asp?TOPIC_ID=15837

Good luck with your decision.
