A quick Google of gone brings me up urth filters are these similar?
I think the likes of Gobe and urth are similar in quality and price. Hoya also.
The cheaper ones can introduce colour casts to your images though I believe.
If you want to get ’serious’ and poorer the start looking at Lee Filters, Formatt Hitech or Kase.
You will also need to decide on whether you want square slide in filters with a holder and adapter or round screw in or magnetic and step up rings if you want to use on different lens threads, which again come with price considerations.
You can like most things go down a rabbit hole. CPL, ND, soft Grad,, hard Grad it goes on And you get poorer!
If I recall Hoya do a screw in circular set with a 3, 6 and 10 stop ND in for about the cost of a Lee or Formatt 10 Stop on its own so could be worth a look for trying out.
I would definitely do some reading and decide what you thinks right for you as certainly with the likes of LEE etc you are buying into a system so need to be sure you’ve gone in the right direction.
For example, I have the Formatt Hitech 85mm filter holder which comes with a CPL and a few step up rings and that cost me as much on its own as the Hoya set with the 3 NDs costs.
Those 3 NDs for my system would set me back about another £250 on top on the £100 ish it cost for the holder and CPL.
Its not cheap but it can be cheap enough if you are just trying it to see.
Me, I bought the filter holder then decided against going all in so now I just have a really expensive CPL!
I do keep toying with the idea of picking some NDs up though.
