I was reminded why I like bigger field of views in my eyepieces, and table tops, like dobsonians are tracked manually up and down. Bigger fields of view make finding targets easier, and tracking them easier.
I do recall aliexpress being recommended for looking at those svbony eyepieces. https://www.amazon.com/Oumij1-Telescope-Eyepiece-Planetary-Astronomical/dp/B08F7KL9NW/ref=sr_1_2?dchild=1&keywords=4.5+planetary+eyepiece&qid=1598001910&sr=8-2 And here's a decent budget 4.5mm eyepiece.
If you wanted to spend a little bit more but not go to ridiculous. Check out the explore scientific 82 degree field of view eyepieces. They go for over 100 but you do get top level field of view and crystal clear views without the insane price tags of televues.
