Chosing right controler/standalone unit + recordbox on Windows 10

Hi,

I'm entering in to the world of DJing and so far I know that Pioneer is the gear to go for. I have checked many of the YouTube reviews of Pioneer DJ gear and especially the Pioneer DJ controllers, but I've never been more confused on what to buy then now. So, I came here for the honest advice on what controller or standalone mixer shoul I buy for startinb DJing in a range up to 800-1200€ which is max I woul spend for the start. My favorit list of controllers are DDJ RR, DDJ RX, but lately I've seen also XDJ RX which is a bit of the budget, but everyone is saying that that is the revolution in controllers. I'm also confused if I shoul go wit controler or standalone mixer, because I'm no MAC user (Windows 10 user) and I'm afraid if I go wit the controller that is only PC based that I will have lots of issues with crashes during DJing. I'm not sure for which 2 deck or 4 deck controller should I go, since my goal is to make samples with fruity loop and mix them within house music. I woul like to know which is most reliable thing and best choice for a begginer- intermediate DJ. I'm intending to roll the music mostly private parties, home studio and some small caffes. It will be more for like a hobby and love to house music. Please advise me on this because I wouldn't like to spend 1000€ or a bit more money on equipment that will give me a hard time when using it with laptop (reliability) or as standalone. Please help me! I'm soon gonna be ready for purchase. One more thing, how reliable is Recordbox software on Windows 10 laptops, because I'm affraid of that then when i purchase for example ddj RX, i won't be able to use it properly!? I have Lenovo Y510p laptop and the ASUS ROG 752VY whic are not bad laptops since each of them were mkre then 1200€ and are more like workstations. Please help and advise me!! Thank you so much in advance.
