Advice on first reflex analog camera

I've been shooting film with a point-and-shoot camera for about a year now, and recently I've been considering switching (or adding) to a reflex camera. Since my budget is limited, I've been exploring second-hand options, but the wide range of choices has been a bit overwhelming. Today, I came across a Pentax P30N priced at €55, and I'm curious to hear your thoughts. Do you think this would be a good entry point, or should I keep searching? Thanks in advance!
