Think mine were 270 ish for 10 weeks, which isn’t brilliant value, but the teacher was very very good. You get a discount if you pay for another set of 10 in advance.
In the class there’s a lot of speaking and putting you on the spot which I found very useful, and then there’s a little bit of homework plus learning hiragana in your own time. Combine it with apps, flashcards etc and you’ll really accelerate your learning.
I finished level 1 part 2 recently and will probably sign up again.
