Re: Ericson 29...2 hours...
Paying for a pro to survey a $3K boat seems kind of silly or, rather, cost ineffective to me. There are a couple of "stickies" here that give you info on doing your own survey. I'd print them and take them to the boat & do your own. Don Casey has a book out on the subject as well.
I would get it hauled though rather than having a diver look at it. A 1/2 lift (out, in the slings for an hour or two and back in) doesn't cost much and if it needs the bottom done you can simply continue to a full lift & block with no loss.
Your pics didn't show them but I'd be primarily concerned about the condition of the bulkheads re: chainplate attachments - are they water damaged?
Also, I don't know if those Ericsons have inside or outside ballast - if it's outside, what is the condition of the bolts and the seam on the outside?
It certainly looks like it's worth spending several hours investigating the boat - it may just be a screaming deal.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
