I bought a set of 8 Marples tools when I started, and they still get used. I've added to the collection since. But if I was starting out again and buying on a budget I think I would choose just the essential few from a reputable manufacturer. If you decide to give turning a go then you could choose either spindle or faceplate turning to start with, not both. That means you don't need so many tools - for example no roughing out gouge or skew for faceplate work, and no scrapers or bowl gouge for spindle work. That might allow you to get good quality tools (possibly second hand?) and keep within your budget.
Also, there is enough to get frustrated with when starting a new hobby without finding your tools are to blame, and I think cheap turning tools will be a major source of frustration. If you decide to go in for turning as a serious interest then you won't want to use cheap tools, so they will be a waste of money since you will be replacing them with decent stuff. If you decide turning is not for you then you'll need to sell on the cheap tools - who would want them? But you try advertising Crown / Ashley Isles / Sorby etc tools and see what the response is like.
My personal opinion - for what it's worth. Others may disagree.
Finally, I don't actually know what Marksman tools are like. You may get some favourable comments from other forum members. If the comments are unfavourable though, then don't waste your much needed funds.
