Your budget of $200 each should allow you to pick up some good eye pieces on this forum’s classifieds
Plössl’s eye pieces at 50deg AFV are usually the lowest cost due to being a base line eye piece ( less glass ) with the exception of Televue.
Obviously as your AFV increases , costs increase ( more glass ) and the same with focal length ( more lens / glass and coatings )
AFV usually start at 50 degrees ( Plössl’s) and go all the way up to 110 degrees which are the high end Televue 3.5mm and 4.5mm.
Entry level brands
Skywatcher , Saxon , Bintel ( GSO )
Mid range
Celestron , Baader , Pentax , Takahashi
High end
Televue , Pentax , Explore Scientific
There are many more brands but these are just a few commonly used by amateur observers.
At this stage I’d buy the following 3 eye pieces -
7mm to 10mm
15mm to 20mm
25mm to 32mm
Obviously try to buy at least 1 eye piece with a minimum of 60 to 70 degree AFV but again your budget will decide on this option.
Also if you wear glasses to observe try to buy eye pieces with an eye relief of at least 18mm to 20mm.
A moon filter would be an advantage when doing lunar observing. Also planetary filters are a must especially when observing Saturn and Jupiter.
Hope all the above is helpful
NB: I started observing full time in 2016 and ventured into Astrophotography in 2018 so I’ve only been a part time observer over the last 5 or 6 years , most of my time these days is spent on Deep Space Long Exposure Astrophotography. However I do still enjoy observing at my dark site with the SW 12” Goto Dob and my array of Televue eye pieces and accessories.
I’d say I’m only a part time observer.
Good luck with your astronomy journey !!
