I agree with those who suggest trying to improve the motions on your current Dob first.
However, if you really want to swap your scope for something else I'd not recommend the 150mm Synta. The F/5 version has heaps of false colour (inevitable) and the F/8 version still shows much colour on bright objects, e.g., naked eye planets. Additionally, the F/8 version is ~4ft long, weighs ~10kgs (scope alone, no rings, dovetail or finder) and is very nose heavy (the balance point is ~1/3rd of the way from the objective lens to the focuser). That means the mount it sits on has to be strong to cope with the scope's moment arm and tall to keep the eyepiece far enough off the ground. I'd say something like an EQ6 at minimum. A 120mm Synta F/8 is a hugely more manageable scope in every way than its bigger sibling.
More manageable than both Synta scopes is something like my Vixen 4" F/9 ED refractor (similar size to a Synta ED100). My Vixen is about 38 inches long, weighs a little over 4kgs with rings and dovetail plate and can be used on a fairly light weight mount. It also requires almost no time to cool down. If you are happy with what you can see with 4" of aperture then I think a 4" ED refractor is about as hassle free a scope as you can get. I use mine when going out for quick looks.
Best of luck with whatever you choose!
