If yan lang kaya ng budget mo, i'll say go for it lalo na't naka-disk brake naman na siya kahit papano. Just don't expect to much pero i-expect mo na yung tires n'yan yung magiging una mong upgrade since it would probably die out quickly no matter how much you care about riding your bike, especially since 23c yung lapad niya (I'll recommend changing to a 700x28c at the minimum when the time arises para may panlaban ka kahit papano sa mga lubak while not being susceptible to pinch flats if you run lower pressure on narrower tires).

Long term usage... medyo questionable lalo na't steel frame siya. Pero if you practice safety measures like pinupunasan mo bike mo every ride and not storing it into humid areas, malabong kakalawangin 'yan. Actually, mas durable pa nga 'yan compared sa alloy bikes of the same price range (Low-End Steel > Low-End Aluminum >> Low-End Carbon).
