As others have said, it's probably going to depend a lot on what sort of sailing you want to do. If by day trips you mean a day messing about close to the shore, then a small dinghy (like the GP14 mentioned earlier) would be ideal, and shouldn't set you back too much.
If on the other hand you want to travel somewhere on a day trip then you'll want somthing a bit more seaworthy (and perhaps an auxilliary outboard). A wayfarer would be OK for this (and I know a couple of people who've gone very far offshore in one), but somthing with a bit more ballast would be better.
My absolute favourite day boat is a Devon Yawl. Very sea worthy with a big heavy centreboard and two masts, which gives you a lot of options if the wind gets up. They are very hard to get hold of though, and they are't cheap. Drascome also have a very nice range of good seaworth boats tthat have a very traditional feel to them, and might be a bit cheaper.
