Hi Gavin and Welcome
An 200mm / 8" newt, either f5 or f6 if well collimated will give you better views of the moon and planets than a fast f5 refractor, though they are not as bulky, the refractors will have a degree of colour fringing that the reflector wont have. That is , unless said refractor is an Apochromat, which is much more expensive than an Achromat.
The newts you are thinking of are most likely Skywatcher or GSO and out of the box they should be collimated already but checking occasionally and adjusting if necessary is not as big a deal as it may sound. once you have done it a few times you can almost do it in your sleep, so to speak. They are also great for DSO hunting, especially if you can get to a dark site and will reveal 1000s' of faint fuzzy objects and the brighter objects will impress.
Have fun.
Jeff
