As the guys above say, it really depends on your budget. But there no point blowing all your money on an expensive microphone, a top of the line audio interface, good neutral sounding pair of monitoring headphones, and a decent set of powered studio monitoring speakers, if you haven't got your recording space sorted. And when I say "sorted", I mean making sure your recording space is as soundproof from outside noise source ingress as possible and then treating the space you're recording in against reverberation. This is definitely where you should spend the lions share of you budget, especially if you're you long term goals is to level up your gear to the types of industry standard mics like the Neumann U87 or even the TLM 103 which as stated above are far less forgiving of a less than ideal recording space.
Now, as mentioned above you can help treat the reverb in your space with the likes of sound blankets (work very well but are expensive), foam tiles (not really anywhere near as effective as people assume for the price), or my personal favourite choice Rockwool acoustic insulation (the stuff that is usually used in the construction of professionally made acoustic panels) it works great to deaden reverb and can be got relatively easily and cheaply for the amount of coverage you can get out of a few packs, but you will need some DIY skills to either make you own panels to treat your space (if you don't have outside noise ingress issues) or if you need more outside noise isolation, to build yourself a hard walled booth to then completely line inside with the Rockwool (the thicker the better, and try to leave an air gap between the outer wall and the Rockwool slabs if you can as this helps increase it effectiveness).
Now on to gear, I'd start out choosing a decent reasonably priced audio interface that should last you a few years like a Focusrite Scarlett Sole 3rd Gen or the EVO 4 by Audient, you can also get either of these as "Studio Bundles" sets with a half decent microphone and okay set of closed back headphones for monitoring plus all the cables (you will need to source you own mic stand... and shock mount with the Focusrite set, but the EVO 4 recording bundle does has a shock mount with it's mic). The mics in the bundles aren't the best and will need upgrading in time, but I know quite a few people who have used (and still use) those mics that come as standard for regular work for the BBC and the like. After that, the best bang for you buck is probably the Audio Technica AT2035 or the Neat King Bee II (which has now been released and will hopefully be available in the UK very soon!) Although if you have a less than Ideal space with a little bit of noise ingress and still a bit of reverb you might be better suited to a shotgun microphone rather than a large diaphragm condenser, in which case my top budget picks are probably the Audio Technica AT875R or if you can afford spend a bit more then the Sennhieser MKE600, and if you can afford a bit more than that then go for the Ride NTG5 (it sounds amazing and on my voice even better than the industry standard shotgun microphone the Sennhieser MKH416).
Anyway, I hope that helps a little rather than confuses the situation further!
Take care and best of luck setting up your space!
