Is it worth getting a preset handle for eclipse lines or does no body really use them? Also ive see that you can get
Triple Action Handle for these guys. Has anyone had any experience with these new handles...?

Madbrush already answered this, but I'll totally second what he said. I'm a newbie, and I did buy a preset handle for my HP-CS. It looks nicer than the stock handle, and the shape & balance are IMO more comfortable, but that's the extent of its pluses. I've found preset handles in general (I have two brushes with them now) to be significantly less efficient than just learning to control lines manually. And learning paint reduction is the lions share of that anyway, rather than trigger control (where it acts more as a crutch than training wheels), so it isn't really useful IMO.
And what Madbrush says about it interfering with manually pulling the needle back for flushing is 120% true with the Eclipse handle in particular. The Eclipse's preset knob only screws back as far as the needle's base trigger-based travel before it comes loose from the handle. W/ the Eclipse, you end up having to basically remove the preset knob from the handle in order to do that kind of flushing, making it less efficient than the stock handle (my Badger Sotar's preset handle goes back a lot further, and so doesn't have this problem).
In fact one thing I've noticed watching really advanced/experienced airbrush artists is that a lot of them seem to prefer working without a handle entirely. I assume this is to make grabbing the needle for flushing between colors that much simpler. Also with the Eclipse specifically, working with the handle off lets you adjust the trigger spring to a much lighter tension, as having the the handle screwed on blocks the spring guide from being backed up past a certain point (another issue my Sotar doesn't have).
I'd also recommend against a MAC valve. I bought an in-line one because I thought it would add flexibility to my setup (against the advice of some old forum hands here, at that), but it really just added redundant complication. If your regulator is within reach, that's all you need. A good regulator will give you more precise and repeatable control, and you only have to deal with one setting instead of juggling two separate ones which control the exact same thing anyway. IMO you only need a MAC valve if you're switching between paint brands/types a lot in the same session. Otherwise you don't really need to fiddle with pressure beyond occasional start-of-session calibration.
In fact, I don't even use quick-connectors anymore, since I prefer pen-like handling with a light hose and as short a stalk as possible. I rarely use multiple brushes in one session, and the speed difference between quick connect and screw connect is negligible enough that it wouldn't really be meaningful unless I was constantly switching between brushes... in which case a manifold setup would seem to be the win/win option. I've kinda come to feel quick connects are more for extending the stalk for those that prefer a bit of pseudo-pistol grip than they are for efficiency.
