To buy or not to buy-needs transom

I came on here because a 1974 V20 was offered to me for $1500/negotiable, boat, motor and trailer. It has an early 90s Mariner 125 on it. The boat is in decent shape except for the soft transom. After searching a little on here, I saw there is a problem with the transoms. Is it worth buying this boat and paying someone to fix it? I don't have to time to repair it myself. Anyone know a place in central NJ that could do the repair? I called one place and they said no less than $4500. Thanks - Mark
