An Anthropic sub is $200/mo, max. I only use open weight models, but the reality is that $200/mo Anthropic sub is way better value per dollar than an open weight model. I use open weight models for other reasons, but I have to limit myself to flash, and I am very controlling of which providers I use to keep the price down, and I still come out a little worse than Anthropic for my monthly bill.

I don't know how you use your agents and what kind of work you are doing, but my experience is that in terms of pure output per dollar, you cannot beat an Anthropic subscription with an open weight model.
