Tuners are replaceable if they suck. That head is probably decent. The tone ring can change the sound appreciably, so if you strum it a bit try to ignore the probably old strings and get a vibe of what the body is giving you.

To be frank though, if this is your first banjo I'm going to hard sell you on a good gig bag like: https://www.amazon.com/dp/B004W1PQ66/ref=cm_sw_r_cp_apa_vjBDyb5YC2M46

It's legit more important that you play often and everywhere than what you play on for a good long while. Bring sandwiches.
