A blacrolite with case and stand? For $100 it's a nice package. $150 is WAY too much. I paid $75 a few years back for mine with just the case and the muffler was missing. The '60s Acrolites were nice (I had one) but mid '70s and up until the Black versions appear to be affected by QC or material differences, some nice sounding and some not so nice. Muffler was $25 (got it at Woodwind & Brasswind) so there is a bargaining point if this one is missing.
I put a generic 42 strand wire set on mine, replaced the muffler (I like them), run Attack TB Sig. heads, and recently threw a S-hoop on batter side. Jury is out on the S-hoop overall but the cross-stick is a huge improvement. It's my middle of the road snare, used for mid to loud volume gigs.

They have creeping up in price. 150 isn't way high but you can do better.
Personally I yank the mufflers myself. I like an open sounding kit.
