I use a $40 Samson GoMic. I've been recording all of my YouTube videos with this mic since 2014. I've messed around with EQs in Logic (my DAW) to find a sound that best suits what I'm looking for. I've recently upgraded to a Zoom Q8 which has it's own XY pattern mic, I'll be giving that a try for recording my sound. But I've got good use out of the Samson mic. I'd suggest you mess around with the EQ in your recording software.
It takes a bit of time to learn what frequencies you need to alter to get the sound you want, however when you find it save the settings! It will take time...so be patient and experiment. There's no magic advice other than hard work, and get yourself a decent pair of studio monitors to listen back on. I use Mackie $100 monitors (for the pair) that I got on amazon. Not amazing, but does the job and are fairly neutral sounding.
