Technically, LSA can include the heavier powered parachutes and you can
already buy them "ready-to-fly" for under US$45k:

But no doubt you mean traditional fixed-wing aircraft - which gets tougher.
Here are a couple of the lowest cost ready-to-fly models I know of at US
$65k:

There are a bunch of kits that allegedly have sub-1000 hour build times
that can be had for under $45k. (The Savannah kit for example can be had
for under $45k and allegedly built on the order of about 300 to 400 hours.)
