New member on the hunt! Please help!

Hello everyone! I'm new to the forum but am a long time reader. I've been sailing my whole life, but largely due to the great community and wealth of info in this forum, I'm officially on the hunt for my first DS1!
I've got an appointment set to go see a boat about an hour away. Mostly everything seems good on the boat, but I pointed out to the seller that in one of the photos it's clear that there are no coamings. He said he got the boat that way and had no idea there were supposed to be any. Of course I will have to replace these (formerly a professional carpenter, thankfully!), But I'm worried that the side decks might have already been structurally compromised. Should I look for anything specific, or will damage be obvious if it's there? There are also no centerboard supports shown. Not sure if they are temporarily not in the boat or if they don't exist, but that also worries me that this boat may have hidden structural issues.
Second question is price. The seller is asking $1500. Boat has paperwork, all working rigging, clean trailer w/ title, roller furling jib (my preference), and a 4 yr old 4hp outboard (a little oversized, as I've read, but I want a little kick here on the long island sound). The wood for coamings and some epiphanes varnish will run me about $100 and 2 evenings of work. I was thinking of offering him $1100. Too low, too high? I don't want to low-ball anyone, but I also don't want to get a bad deal. I feel like I always read these tales of everyone on the forum getting their fully loaded DS1 for $8 and a bag of pita chips from some poor widow who conveniently lives 3 blocks away, but those stories sometimes seem a bit too good to be true.
Any guidance you can provide would be much appreciated! Can't wait to get on the water! I've had too many naps on keelboats. Need the thrill of a tiller and CB!
