I don't know what kind of specs you're looking for for your system, but I've been very happy with my netgate.
Though it's still close to $200 for the lowest model, but comes with support if your not really sure what your doing.
Netgate 1100 $189

oof. All I can do is thank you for the hard work that anybody's put into this, and I'm sad to see it go because I've been using this with my keypass for probably about a year now.
Really hoping the Graphene OS lawsuit allows for some Options to open up again!
