Get a used one.
As long as you don't want high end graphics support - "gaming laptop", for which FreeBSD wasn't the best choice, or need a large full power CPU for lots of large compiling jobs, which IMO ain't no laptop for anyway, a good, solid used one will do the job, saves you a lot of money, and is more probable to be supported than any brand new hardware (see the according sites for which HW is supported.)
You may exchange the drive(s), add some more RAM, or need to exchange the WLAN module (~twenty bucks), but anyway it was worth a thought.
